High performance 1.5W pHEMT Distributed Power Amplifier with Adjustable Inter-Stage Cascaded Network for 10÷2000 MHz
A new topology of high performance pHEMT distributed power amplifier is presented. An adjustable inter-stage cascaded matching network between two non-identical 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 (plusmn2 dB) for frequency ranges (10+2000 MHz) are achieved. Moreover, stability analysis through pole-zero identification indicated, for this topology, and acceptable stability margin even under large-signal operation.
