HMC993LP5E
v01.0214
RF AUTOMATIC GAIN CONTROLLER
(RF-AGC), 700 - 3000 MHz
Application Information
TE
The HMC993LP5E is a complete high performance Automatic Gain Control (AGC) solution, housing a Variable Gain
Amplifier (VGA) core and a control core in a single package. Its unique VVA technology provides constant OIP3 over
the entire control voltage range. The HMC993LP5E greatly simplifies the design of gain control loops by increasing
the integration level and reducing the number of required circuit elements. The VGA core of the HMC993LP5E is
composed of two identical voltage variable attenuators followed by two gain block amplifiers which operate from 0.7
to 3.0 GHz. The HMC993LP5E’s control core features a high accuracy log detector. As shown in the functional block
diagram, the HMC993LP5E combines all of these cores in a highly compact 5 x 5 mm plastic package, and offers an
easy-to-use, temperature stable AGC solution.
LE
The HMC993LP5’s VGA core has a flexible structure where a single attenuator (22.2 dB at 1900 MHz) or two attenuators (33.6 dB at 1900 MHz) can be used depending upon the dynamic range requirement. Inputs and outputs of
the HMC993LP5E’s attenuators and first amplifier (ATTIN1, ATTOUT1, ATTIN2, ATTOUT2, AMPIN1, AMPOUT1) are
broadband matched to 50 Ohm single-ended and require only external DC blocking capacitors over the entire frequency band of operation. The input of the HMC993LP5E’s log detector (RFDETIN) is also broadband matched to 50
Ohm single-ended and does not require any matching components. Input and output of the HMC993LP5E’s second
amplifier (AMPIN2, AMPOUT2) need power matching components for key application frequencies. Refer to application circuits for example application frequencies.
B
SO
The HMC993LP5E requires a single 5V supply with adequate power supply decoupling as recommended in the application schematics.

RF AUTOMATIC GAIN CONTROLLER
(RF-AGC), 700 - 3000 MHz
The HMC993LP5E’s VGA core can be configured with one or two variable attenuators followed by two fixed gain
amplifiers for different control ranges as shown in Figure 1a and Figure 1b (basic connections are not shown). Note
that the link between VCTRL and DETOUT pins must be broken for correct VGA Operation. The VCTRL pin should be
used to set the attenuation of the HMC993LP5E.
O
Gain Control Interface VCTRL
The VCTRL pin is the gain control pin common to both of HMC993LP5E’s identical voltage variable attenuators. The
VCTRL gain control voltage ranges between 1V and 4V. A VCTRL control voltage of 1V provides the lowest attenuation,
while 4V provides the highest attenuation.
Figure 2 represents the VGA operation of HMC993LP5E with two attenuators and two amplifiers for different gain control
voltages applied to the VCTRL pin. The output power increases linearly with the input power until the power saturation is
reached when the VCTRL voltage is constant. The useable input power range of such a system is limited by the saturation level of the final stage amplifier. So the input power level required for power saturation and the dynamic range of the
HMC993LP5E’s VGA is defined by the value of the gain control voltage applied to the VCTRL pin. Refer to the Figure 2
for the useable input power range at different VCTRL levels.
When VCTRL=1V, the gain of HMC993LP5E’s VGA with 2 attenuators is 21.5 dB at 1900 MHz. The input power required
for 1 dB compression point at the output is given by: Pin1dB = Pout1dB – Gain (dB) + 1 = 25 – 21.5 + 1 = 4.5 dB.
When VCTRL=2V, the gain of the HMC993LP5E’s VGA with 2 attenuators is 11.7 dB at 1900 MHz. The input power
required for 1 dB compression point at the output is given by: Pin1dB = Pout1dB – Gain (dB) + 1 = 25 – 11.7 + 1 = 14.3
dB.

Therefore, increasing the VCTRL pin voltage reduces the gain of the HMC993LP5E’s VGA and increases input power
level required for power saturation. When the input signal is weak, the attenuation level of the variable attenuators
should be reduced. When the input signal is large; the attenuation level of the variable attenuators should be increased
to achieve a constant output level.
The gain control performance of the HMC993LP5E at 1900 MHz is shown in Figures 3. The HMC993LP5E provides
22.2 dB of gain control range with a maximum gain of 26 dB when it is configured in 1 attenuator + 2 amplifiers mode,
and similarly a 33.6 dB of gain control range with a maximum gain of 21.5 dB of gain when it is configured in 2 attenuators + 2 amplifiers mode. The HMC993LP5E’s VGA has a very flat linear-in-dB gain control characteristic with a slope of
-12.97 dB/V for the 2 attenuators configuration and -7.28 dB/V for the 1 attenuator configuration. The log-linearity error
of the HMC993LP5 VGA is typically less than ± 2dB over the entire gain control range.

referred distortion (IIP3) characteristics of the HMC993LP5E’s VGA are dependent on the gain control voltage VCTRL.
When the attenuation level of the variable attenuators is set to minimum (maximum gain state), the noise figure of the
HMC993LP5E’s VGA is minimized; however the IIP3 is degraded to minimum as well. The noise figure and IIP3 of the
HMC993LP5E’s VGA increases with the attenuation level of the variable attenuators.
For low attenuation levels, the noise contribution from the VGA is important since the input signal is weak. For high atten-

For low attenuation levels of the variable attenuators, IIP3 is less important since high gain of whole VGA improves distortion performance at its output (OIP3). For high attenuation levels of the variable attenuators, IIP3 is more important
because of low gain of whole VGA. The distortion performance of the HMC993LP5E’s VGA at 1900 MHz is shown in
Figure 4. The HMC993LP5E’s VGA provides an almost constant OIP3 of up to +45 dBm in any state when it is configured in one attenuator and two amplifiers mode.

uation levels of the variable attenuators, the noise contribution from the VGA is less important and the noise requirement
of the VGA is relaxed since the input signal is high. The noise figure performance of the HMC993LP5E’s VGA at 1900
MHz is shown in Figure 4. The HMC993LP5E’s VGA delivers a noise figure of 9.8 dB in its maximum gain state when it
is configured in 1 attenuator + 2 amplifiers mode.

In AGC amplifier configuration, the input signal is amplified by the HMC993LP5E’s VGA. The output of the HMC993LP5E’s
VGA core is fed back to the input of the HMC993LP5E’s log detector (RFDETIN) through an external coupler or attenuator to drop the maximum and minimum output level of the HMC993LP5E’s VGA to within the dynamic range of the
HMC993LP5E’s log detector. The HMC993LP5E’s log detector produces a voltage at the output of the log detector
(DETOUT) proportional to the output power level of the HMC993LP5E’s VGA. The high impedance output pin DETOUT
is connected to the gain control pin VCTRL of VGA to form the AGC loop. The VSET pin is the constant output power set
point of the AGC amplifier. As a result of negative feedback, the gain of the VGA is automatically adjusted to maintain a
constant signal power level at the output of AGC amplifier. The output signal power level is determined by the AGC set
point VSET, regardless of the input signal variation.
AGC Set point Interface VSET
In closed loop AGC operation the output power level of the HMC993LP5E is controlled by the VSET pin. An input voltage between 0.2V and 1.2V should be applied to the VSET input pin to control the output power level. Output power vs.
VSET characteristic is shown in Figure 6a and Figure 6b for different input power levels and different coupler ratios used.
The slope of the gain vs. VSET characteristic is 58.3dB/V and it is independent of the coupler ratio used.
The relation between the gain of HMC993LP5E’s output power and VSET pin voltage at 1900 MHz can be approximated
as given in Equation (1) when it is configured in AGC amplifier configuration with 2 attenuator + 2 amplifiers.
Output Power (dBm) = -67.7 + |Coupler Ratio| + 58.3 x VSET

In closed loop operation the HMC993LP5E is able to automatically adjust the RF gain over a gain adjustment range of
up to 33.6 dB at 1900 MHz. The HMC993LP5E’s output dynamic range is a function of both input power level and the
coupler ratio used to close the AGC loop. The combined effect of the input power and coupler ratio on the output power
dynamic range is presented in Figures 6a and 6b.
For high input power levels, the maximum level of output dynamic range is limited by the Psat of the VGA or the highest detectable power level by the log detector. To eliminate any limitations that can arise due to highest detectable log

Similarly, the lower side of the dynamic range is limited by the noise floor of the VGA or the lowest power level detectable by the log detector. To eliminate any limitations on the lower side of the dynamic range, the coupler ratio should be
low enough to translate the minimum VGA output power level to a value higher than the lowest detectable log detector
power level.
Please also refer to the Log Detector section for more information.

Figure 7a shows the output power vs. input power transfer characteristic of the HMC993LP5E over different VSET
voltages for a closed AGC loop configuration. For low and high input power levels the HMC993LP5E attenuation rage
is saturated and the output is a linear function of the input. For input power levels within the dynamic range, the
HMC993LP5E automatically adjusts the attenuation level as shown in Figure 7b to maintain a constant output power
level. When Vset=0.5 V, the output power level is set to -18.7 dBm and the HMC993LP5E’s AGC amplifier provides a
gain control range of 33.6 dB from -40.2 dBm to -6.6 dBm with an excellent ripple within 0.7 dB.

Log Detector
The logarithmic detector of the HMC993LP5E converts the average envelope of RF input power to a proportional DC
voltage at its output (DETOUT), as shown in Figure 8. In detection mode, the DETOUT pin should be connected to
the VSET input. The HMC993LP5E’s logarithmic detector employs a successive compression technology which delivers 50 dB of dynamic range (±1dB) with high conversion accuracy over a wide input frequency range. Note that the
link between DETOUT and VCTRL pins must broken and DETOUT must connected to VSET via 1k Ohms resistor for
LOGAMP operation.
The HMC993LP5E’s logarithmic detector can be used in the controller mode where an external voltage is applied to the
VSET pin to create an AGC loop. The linear-in-dB behavior of the HMC993LP5E’s VGA and logarithmic detector creates
a linear AGC system. For linear operation, the signal fluctuations at the input of the log detector should remain within
the dynamic range of the log detector. In closed loop AGC operation, the HMC993LP5E’s response to large input level
changes is not slew-rate limited, and the speed of the transient response can be adjusted through loop filter capacitors
C4 and C7 (see Figure 5).
To achieve maximum gain adjustment range of the HMC993LP5E, the coupler ratio should be chosen based on the
output power desired. A coupler ratio which translates the output power to the center (~-25dBm) of the usable dynamic

If the linear operation range of the HMC993LP5E is maximized by selecting the appropriate coupler ratio, the
HMC993LP5E can handle larger changes in input level. For example, an input voltage of 0.5 V is applied to the Vset
pin to set the constant output power level to -18.7 dBm. A coupler ratio of ~7 dB can be chosen to provide a maximum
dynamic range of 33.6 dB.

Loop Bandwidth and Response Time
The AGC system has a response time to undesired input level fluctuations. Response time and the stability of the
HMC993LP5E’s AGC loop is determined by C4 and C7 in the application schematic. The HMC993LP5E’s response to
