- Abstract
- Two-stage reactively matched gain cells are applied to design a high-gain multi-octave distributed power amplifier (DPA) in this paper. The proposed reactively matched distributed amplifier (RMDA) structure shows a high gain and high output power performance within a small die size. The DC bias network of each section is simplified to implement the proposed structure in an MMIC and the design guide for the bias network is provided. A 6-18 GHz GaN DPA fabricated with the commercial 0.25-μm GaN HEMT process shows output power reaching 40.3-43.9 dBm with 16-27% PAE. To the best of our knowledge, this is the first demonstration of a GaN DPA using reactively matched gain cells, and it exhibits excellent small-signal gain and RF power performance capabilities among other reported GaN PAs with a multi-octave bandwidth up to the Ku-band. © 2017 IEEE.
