A High Linearity 30-GHz Range SiGe Differential Power Amplifier IC

A 30 GHz-range power amplifier (PA) IC for short-range point-to-point applications is presented in this paper. The monolithic PA design is fully differential and is fabricated in SiGe HBT technology for low-cost applications. Matching networks are based on distributed elements implemented in coplanar waveguide (CPW) structures. The PA is classed for high linearity and measured output power achieved is 11.9 dBm at the 1-dB compression point
