A 1.95 GHz linear power amplifier (PA) in a standard 0.18 m CMOS process is presented. The PA achieves the load insensitivity characteristic up to 2.5:1 VSWR condition and dual-mode operation with a balanced topology. The area of the PA is 1.6 × 1 mm2. With a 3.4 V power supply, the PA provides 40.4 of peak power-added efficiency (PAE) and 35 of PAE at 26.4 dBm of linear output power.
