Description
The MAAM-011112 is a 4-stage amplifier covering
many bands from 20 to 37 GHz with good return
losses, high gain, and good linearity. No external
matching components are required. This amplifier is
internally matched to 50 ohms. The input and output
are DC blocked.
The MAAM-011112 primary applications include
buffer amplifiers in LO chains and driver amplifiers in
transmit lineups for Point-to-Point and Point-to-
Multipoint communication systems.
Pin Designations2
The 3 mm PQFN package has a lead-free finish that
is RoHS compliant and compatible with a 260ºC
reflow temperature. The package also features low
lead inductance and an excellent thermal path.

App Note [1] Biasing
As shown in the Pin Designation table, the device is operated by biasing Vd1, Vd2, Vd3 and Vd4 at 4.0 V. The
corresponding drain currents are set to 75 mA, 35 mA, 75 mA and 150 mA respectively. It is recommended to
use active bias on Vg1, Vg2, Vg3 and Vg4 to keep the currents in Vd1, Vd2, Vd3 and Vd4 constant, in order to
maintain the best performance over temperature. Depending on the supply voltages available and the power
dissipation constraints, the bias circuits may include a single transistor or a low power operational amplifier, with
a low value resistor in series with the drain supply to sense the current. Make sure to sequence the applied
voltage to ensure negative gate bias is available before applying the positive drain supply.
