Abstract

A new topology of high performance pHEMT distributed power amplifier is presented An adjustable inter-stage cascaded matching network between two nonidentical transistors is proposed. The superiority of the topology as indicated by the theoretical discussion is verified through simulation. Gain and PAE of 24 dB and 45-56%, respectively while output power of 32 dBm (+/- 12dB) for frequency ranges (10-2000 MHz) are achieved Moreover, stability analysis through pole-zero identification indicated, for this topolopy, and acceptable stability margin even under large-signal operation.
