A radio frequency power amplifier for 4.8-5.7 GHz has been realized in a 0.35-μm SiGe bipolar technology. The balanced two-stage push-pull power amplifier uses two on-chip transformers as input-balun and for interstage matching. Further, it uses three coils for the integrated LC-output balun and the RF choke. Thus, the power amplifier does not require any external components. At 1.0-V, 1.5-V, and 2.4-V supply voltages, output powers of 17.7 dBm, 21.6 dBm, and 25 dBm are achieved at 5.3 GHz. The respective power-added efficiencies (PAE) are 15%, 22%, and 24%. The small-signal gain is 26 dB. The output 1-dB compression point at 2.4 V is 22 dBm with a PAE of 14%.
