Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based on a set of
16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From these measurements a true Fmin is calculated.
Refer to the noise parameter application section for more information.
2. S and noise parameters are measured on a microstrip line made on 0.025 inch thick alumina carrier. The input reference plane is at the end of the gate
lead. The output reference plane is at the end of the drain lead. The parameters include the effect of four plated through via holes connecting source
landing pads on top of the test carrier to the microstrip ground plane on the bottom side of the carrier. Two 0.020 inch diameter via holes are placed
within 0.010 inch from each source lead contact point, one via on each side of that point.

Figure 20. MSG/MAG and |S21|2 vs.
Frequency at 3V, 60 mA.
Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based on a set of
16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From these measurements a true Fmin is calculated.
Refer to the noise parameter application section for more information.
2. S and noise parameters are measured on a microstrip line made on 0.025 inch thick alumina carrier. The input reference plane is at the end of the gate
lead. The output reference plane is at the end of the drain lead. The parameters include the effect of four plated through via holes connecting source
landing pads on top of the test carrier to the microstrip ground plane on the bottom side of the carrier. Two 0.020 inch diameter via holes are placed
within 0.010 inch from each source lead contact point, one via on each side of that point.

Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based on a set of
16 noise figure measurements made at 16 different impedances using an ATN NP5 test system. From these measurements a true Fmin is calculated.
Refer to the noise parameter application section for more information.
2. S and noise parameters are measured on a microstrip line made on 0.025 inch thick alumina carrier. The input reference plane is at the end of the gate
lead. The output reference plane is at the end of the drain lead. The parameters include the effect of four plated through via holes connecting source
landing pads on top of the test carrier to the microstrip ground plane on the bottom side of the carrier. Two 0.020 inch diameter via holes are placed
within 0.010 inch from each source lead contact point, one via on each side of that point.

Introduction
Agilent Technologies’s ATF-54143
is a low noise enhancement mode
PHEMT designed for use in low
cost commercial applications in
the VHF through 6 GHz frequency
range. As opposed to a typical
depletion mode PHEMT where the
gate must be made negative with
respect to the source for proper
operation, an enhancement mode
PHEMT requires that the gate be
made more positive than the
source for normal operation.
Therefore a negative power
supply voltage is not required for
an enhancement mode device.
Biasing an enhancement mode
PHEMT is much like biasing the
typical bipolar junction transistor.
Instead of a 0.7 V base to emitter
voltage, the ATF-54143 enhancement mode PHEMT requires
about a 0.6V potential between
the gate and source for a nominal
drain current of 60 mA.
Matching Networks
The techniques for impedance
matching an enhancement mode
device are very similar to those
for matching a depletion mode
device. The only difference is in
the method of supplying gate
bias. S and Noise Parameters for
various bias conditions are listed
in this data sheet. The circuit
shown in Figure 1 shows a typical
LNA circuit normally used for
900 and 1900 MHz applications
(Consult the Agilent Technologies
website for application notes
covering specific applications).
High pass impedance matching
networks consisting of L1/C1 and
L4/C4 provide the appropriate
match for noise figure, gain, S11
and S22. The high pass structure
also provides low frequency gain
reduction which can be beneficial
from the standpoint of improving
out-of-band rejection at lower
frequencies.

Capacitors C2 and C5 provide a
low impedance in-band RF
bypass for the matching networks. Resistors R3 and R4
provide a very important low
frequency termination for the
device. The resistive termination
improves low frequency stability.
Capacitors C3 and C6 provide
the low frequency RF bypass for
resistors R3 and R4. Their value
should be chosen carefully as C3
and C6 also provide a termination for low frequency mixing
products. These mixing products
are as a result of two or more inband signals mixing and producing third order in-band distortion
products. The low frequency or
difference mixing products are
bypassed by C3 and C6. For best
suppression of third order
distortion products based on the
CDMA 1.25 MHz signal spacing,
C3 and C6 should be 0.1 µF in
value. Smaller values of capacitance will not suppress the
generation of the 1.25 MHz
difference signal and as a result
will show up as poorer two tone
IP3 results.
Bias Networks
One of the major advantages of
the enhancement mode technology is that it allows the designer
to be able to dc ground the
source leads and then merely
apply a positive voltage on the
gate to set the desired amount of
quiescent drain current Id.
Whereas a depletion mode
PHEMT pulls maximum drain
current when Vgs = 0V, an enhancement mode PHEMT pulls
only a small amount of leakage
current when Vgs = 0V. Only when
Vgs is increased above Vto, the
device threshold voltage, will
drain current start to flow. At a
Vds of 3V and a nominal Vgs of
0.6V, the drain current Id will be
approximately 60 mA. The data
sheet suggests a minimum and
maximum Vgs over which the
desired amount of drain current
will be achieved. It is also important to note that if the gate
terminal is left open circuited,
the device will pull some amount
of drain current due to leakage
current creating a voltage differential between the gate and
source terminals.
Passive Biasing
Passive biasing of the ATF-54143
is accomplished by the use of a
voltage divider consisting of R1
and R2. The voltage for the
divider is derived from the drain
voltage which provides a form of
voltage feedback through the use
of R3 to help keep drain current
constant. Resistor R5 (approximately 10kΩ) provides current
limiting for the gate of enhancement mode devices such as the
ATF-54143. This is especially
important when the device is
driven to P1dB or PSAT.
Resistor R3 is calculated based
on desired Vds, Ids and available
power supply voltage.
R3 =
VDD – Vds
Ids + IBB

VDD is the power supply voltage.
Vds is the device drain to source

Choose IBB to be at least 10X the

current. IBB was chosen to be
2 mA for this example. Using
equations (1), (2), and (3) the
resistors are calculated as
follows
R1 = 295Ω
R2 = 1205Ω
R3 = 32.3Ω
Active Biasing
Active biasing provides a means
of keeping the quiescent bias
point constant over temperature
and constant over lot to lot
variations in device dc performance. The advantage of the
active biasing of an enhancement
mode PHEMT versus a depletion
mode PHEMT is that a negative
power source is not required. The
techniques of active biasing an
enhancement mode device are
very similar to those used to bias
a bipolar junction transistor.

Figure 2. Typical ATF-54143 LNA with
Active Biasing.
An active bias scheme is shown
in Figure 2. R1 and R2 provide a
constant voltage source at the
base of a PNP transistor at Q2.
The constant voltage at the base
of Q2 is raised by 0.7 volts at the
emitter. The constant emitter
voltage plus the regulated VDD
supply are present across resistor R3. Constant voltage across
R3 provides a constant current
supply for the drain current.
Resistors R1 and R2 are used to
set the desired Vds. The combined series value of these
resistors also sets the amount of
extra current consumed by the
bias network. The equations that
describe the circuit’s operation
are as follows.

Example Circuit

R4 = 10Ω
V BE = 0.7 V
Equation (1) calculates the
required voltage at the emitter of
the PNP transistor based on
desired Vds and I ds through
resistor R4 to be 3.6V. Equation
(2) calculates the value of resistor R3 which determines the
drain current Ids. In the example
R3 =23.3Ω. Equation (3) calculates the voltage required at the
junction of resistors R1 and R2.
This voltage plus the step-up of
the base emitter junction determines the regulated Vds. Equations (4) and (5) are solved
simultaneously to determine the
value of resistors R1 and R2. In
the example R1=1450Ω and
R2 =1050Ω. R7 is chosen to be
1kΩ. This resistor keeps a small
amount of current flowing
through Q2 to help maintain bias
stability. R6 is chosen to be
10kΩ. This value of resistance is
necessary to limit Q1 gate
current in the presence of high
RF drive level (especially when
Q1 is driven to P1dB gain compression point).

Noise Parameter Applications
Information
Fmin values at 2 GHz and higher
are based on measurements
while the Fmins below 2 GHz have
been extrapolated. The Fmin
values are based on a set of
16 noise figure measurements
made at 16 different impedances
using an ATN NP5 test system.
From these measurements, a true
Fmin is calculated. Fmin represents the true minimum noise
figure of the device when the
device is presented with an
impedance matching network
that transforms the source
impedance, typically 50Ω, to an
impedance represented by the
reflection coefficient Go. The
designer must design a matching
network that will present Go to
the device with minimal associated circuit losses. The noise
figure of the completed amplifier
is equal to the noise figure of the
device plus the losses of the
matching network preceding the
device. The noise figure of the
device is equal to Fmin only when
the device is presented with Go.
14
If the reflection coefficient of the
matching network is other than
Go, then the noise figure of the
device will be greater than Fmin
based on the following equation.
NF = Fmin + 4 Rn
|Γs – Γo | 2
Zo (|1 + Γo| 2) (1 - |Γs| 2)
Where Rn /Zo is the normalized
noise resistance, Γo is the optimum reflection coefficient
required to produce Fmin and Γs is
the reflection coefficient of the
source impedance actually
presented to the device. The
losses of the matching networks
are non-zero and they will also
add to the noise figure of the
device creating a higher amplifier
noise figure. The losses of the
matching networks are related to
the Q of the components and
associated printed circuit board
loss. Γo is typically fairly low at
higher frequencies and increases
as frequency is lowered. Larger
gate width devices will typically
have a lower Γo as compared to
narrower gate width devices.
Typically for FETs, the higher Γo
usually infers that an impedance
much higher than 50Ω is required
for the device to produce Fmin. At
VHF frequencies and even lower
L Band frequencies, the required
impedance can be in the vicinity
of several thousand ohms. Matching to such a high impedance
requires very hi-Q components in
order to minimize circuit losses.
As an example at 900 MHz, when
airwwound coils (Q > 100) are
used for matching networks, the
loss can still be up to 0.25 dB
which will add directly to the
noise figure of the device. Using
muiltilayer molded inductors with
Qs in the 30 to 50 range results in
additional loss over the airwound
coil. Losses as high as 0.5 dB or
greater add to the typical 0.15 dB
Fmin of the device creating an
amplifier noise figure of nearly
0.65 dB. A discussion concerning
calculated and measured circuit
losses and their effect on amplifier noise figure is covered in
Agilent Application 1085.
