S-band SSPA for multicarrier applications

A light weight, low distortion SSPA at S-band for multicarrier signal operation has been developed. The SSPA uses the MMIC chips for the low level amplification section and hybrid PHEMT devices for the medium level and high power level sections. The SSPA exhibits at class A operation an output power of 3W, a noise power ratio (NPR) higher than 14dB with an associated PAE of 23% over the frequency band 2.16 - 2.20GHz.
