A Compact 8W S/C-Band MMIC Power Amplifier Designed for CW Telemetry Applications
01 January 2006
The development of a compact S/C-band PHEMT MMIC power amplifier is reported. The MMIC is a single-biased two-stages HPA with a 15 mm gate-width output transistor. In the 3.5-4.0 GHz frequency bandwidth, CW output power is 39.0 plusmn 0.25 dBm, associated gain is 16.5 plusmn 0.25 and PAE ranges from 30 to 35 %; in pulsed operation mode (10% duty cycle), for the 3.5-4.3 GHz frequency bandwidth the output power is 39.5 plusmn 0.2 dBm and the associated gain is 19.5 plusmn 0.2 dB
