AM143440WM-XX-R

AMCOM’s AM143440WM-BM/EM/FM-R is part of the GaAs HiFET MMIC power amplifier series. This high efficiency MMIC is a 2-stage GaAs pHEMT power amplifier biased at 10 to 14V. The input and inter-stage matching networks cover 1.4 to 3.4GHz. This MMIC requires output external matching to your band of interest between 1.4GHz to 3.4 GHz to provide maximum bandwidth flexibility. As an example, one of the available evaluation boards has over 20dB gain, 8 watts (39dBm) saturated output power over the 1.5 to 1.8GHz band at 12V. The other evaluation board at 2.0 to 3.0GHz achieved 19dB gain and 39dBm 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 AM143440WM-FM-R is the AM143440WM-BM-R mounted on a gold plated copper carrier. The EM package has the same footprint as the FM with straight leads and a Copper/Tungsten flange instead of the Copper flange. There are two screw holes on the flange to facilitate screwing on to a metal heat sink. This MMIC is RoHS compliant.
