A new topology distributed power amplifier (DPA) is presented to maximize DC-RF conversion (i.e. for high output). The topology is featured by vectorially combined current sources when loading power transistors into a distributed output and input networks using impedance termination values gathered by device load pull. Broadband impedance transforming filter with Real Frequency Technique (RFT) i s pro posed to transform the DPA output impedance i.e. 12 Ω to 50 Ω termination over the frequency band of 100-2200 MHz.
