AM15354WM-BM-R AM15354WM-EM-R AM15354WM-FM-R November 217 DESCRIPTION AMCOM s AM15354WM-BM-R AM15354WM-EM-R and AM15354WM-FM-R are part of the GaAs HiFET MMIC power amplifier series. It is a 2-stage GaAs HIFET PHEMT MMIC power amplifier. It is fully matched to 5-ohm at both input and output, covering 1.5 to 3.5GHz. The MMIC has 21dB gain and 38.5dBm output power at 14V. The BM package RF and DC leads are coplanar with the bottom level of the package, which serves as ground, to facilitate low-cost SMT assembly to the PC board. Because of high DC power dissipation, we strongly recommend mounting this device directly on a metal heat sink. The FM package is the BM package mounted on a copper flange carrier. The EM package has the same footprint as the FM package 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. Both MMICs are RoHS compliant.

TEST CIRCUIT for BM package Important Notes: 1- The MMIC should have a good heat sink to avoid overheating. MMIC should be attached on direct ground for lowest junction temperature. 2- If surface mount is used, use PC board thickness < 1mils and ensure vias are filled with solder or metal to lower PCB heat resistance. For surface mount the MMC should be de-rated to a maximum +1V bias. 3- Recommended current biases are 3mA & 1mA for the first and second stages respectively. 4- Do not apply Vdd1 & Vdd2 without proper negative voltages on Vgs1 & Vgs2. 5- The currents flowing out of the Vgs1 & Vgs2 pins are less than 2mA & 12mA at P1dB.
