A completely integrated 1.3 W power amplifier in silicon for 1.9 and 2.4 GHz wireless and mobile communications is presented for the first time. The chip is implemented in a 25 GHz fT, 0.8 µm, three layer interconnect silicon bipolar production technology (SIEMENS B6HF). The MMIC is designed for 3.4 to 5 V battery operation at 1.9 GHz, and delivers 0.4 W (26 dBm) to 1.3 W (31.1 dBm) of output power with up to 33% power-added efficiency. The amplifier is also suitable for the 2.4 GHz band with slight performance loss.
