VHF Modules Combine Driver and Output Stage
Consisting of a driver and an output stage, a pair (10 watt and 40 watt) of wide-band VHF power amplifier modules from M/A-COM simplifies design in mobile, portable, and base station systems for microwave and RF applications. The 10-W MAPM-020512-010C00 is a dual-stage module with over 20 dB of gain, accepting an input of 30 V and providing an output of 20 W with a bias current of 1 A. The 40-W MAPM-020512-040C00 includes a DC gate bias pin for the MOSFETs rather than an ALC control pin. The supply voltage is 30 V, input power 10 W, output power 30 W, and bias current is 3 A.
