GaAs MMIC
Power Amplifier
DESCRIPTION
AMCOM’s AM142540MM-BM/FM-R is part of the GaAs HiFET MMIC power amplifier series. It is a 2-stage GaAs
MESFET MMIC power amplifier biased at 14V. The input and inter-stage matching networks cover 1.4 to 2.5GHz.
The MMIC output requires partial external matching to your band of interest between 1.4GHz to 2.5GHz to provide
maximum bandwidth flexibility. The output matching can be designed to cover any 400MHz bandwidth in the 1.4 to
2.5GHz band. As an example, one of the available evaluation boards has over 25dB gain, 10 watts (40dBm)
saturated output power over the 1.4 to 1.8GHz band at 14V. The other evaluation board for 2.1 to 2.5GHz achieved
23dB gain and 37dBm output power at 12V.
This MMIC is in a ceramic package with both RF and DC leads at the lower level of the package to facilitate low-cost
SMT assembly to the PC board. When mounting directly to PCB, please see application note AN700 for instructions.
Because of high DC power dissipation, we strongly recommend to mount these devices directly on a metal heat sink.
The AM142540MM-FM-R is the AM142540MM-BM-R mounted on a gold plated copper flange carrier. There are
two screw holes on the flange to facilitate screwing on to a metal heat sink. This MMIC is RoHS compliant.

NEGATIVE CURRENT REQUIREMENT
In order to maximize the bandwidth and linearity, this product has built-in feedback resistors on-chip. The product
will draw negative current in the Vgg circuit through these resistors. The Table below shows the negative current
values.
The typical negative currents for different Vdd are shown in the table below. The actual Vgg should be adjusted to
have an Idd of about 1.5A. The actual negative current value varies depending on Vgg and may also vary due to
MMIC process variation.
