Description
The MAAM-011100 is an easy-to-use, broadband,
general purpose variable gain amplifier. Its over
30 dB gain range is controlled by a single control pin
and 50 Ω match is maintained over all settings.
The MAAM-011100 operates from 400 MHz to
20 GHz and features flat gain control from +10 dB to
-20 dB. At maximum gain setting (VC = Open) it
delivers up to +18 dBm power and under 5 dB noise
figure. Both reduce proportionally as gain is reduced
with VC. The input IP3 exceeds +15 dBm at max/min
gain settings. The device is typically biased with a
VD = +5 V, VG = -0.5 V, and a control of 0 V to -2 V.
Typical current is 70 mA with VG at -0.5 V
The MAAM-011100 is ideally suited for use as a
power amplifier driver, gain trimming block, or
temperature compensation in the receive or transmit
mode.
This device is assembled in a leadless 1.5 x 1.2 mm
package that can be handled and placed with
standard pick and place assembly equipment.

Static Sensitivity
These electronic devices are sensitive to
electrostatic discharge (ESD) and can be damaged
by static electricity. Proper ESD control techniques
should be used when handling these devices.
5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. MACOM does not recommend sustained operation near these
survivability limits.
7. Operating at nominal conditions with T J ≤ 150°C will ensure
MTTF > 1 x 106 hours.
8. Junction Temperature (T J) = TC + ӨJC * ((V * I) - (POUT - PIN))
Typical thermal resistance (ӨJC) = 67°C/W
a) For T C = 25°C,
TJ = 47°C @ 5 V, 70 mA, POUT = 15 dBm, PIN = 6 dBm
b) For T C = 85°C,
TJ = 107°C @ 5 V, 70 mA, POUT = 15 dBm, PIN = 6 dBm

Application Information for DC & pins
Recommended PCB Layout
For proper MAAM-011100 operation a DC voltage
must be applied at the VG (-0.5V) and VD (+5 V) pins
in that order. Adjusting VG from -0.2 V to -0.6 V will
change the quiescent current which can effect power
and linearity if set below or above 70 mA.
The gain of the MAAM-011100 is controlled with the
VC pin. The gain reduction is almost linear with VC
between 0 V to -2 V. Below -2 V internal ESD
protection diodes will draw increasing current. The
nominal open circuit voltage at the VC pin is +1 V
and produces maximum gain and power. Limiting
applications and zero crossing adjustment can be
done by adjusting the VG and VC pins together.

9. MACOM recommends using Murata part BLM15GG471.
To bias properly, a DC voltage must be applied at
the output pin. Typically this is done with a 2
element bias network that consists of a choke and a
DC blocking capacitor. We recommend a ferrite
bead for the main bias choke and quality capacitor
for the DC block. A simple 1 KΩ resistor can be used
as a RF choke for the negative VG as applied to the
input pin.
It is recommended that the total ground (common
mode) inductance not exceed 0.03 nH (30 pH). This
is equivalent to placing at least four 8-mil (200 µm)
diameter vias under the device, assuming an 8-mil
(200 µm) thick RF layer to ground
