Abstract :
A broadband power amplifier operating from 0.8 GHz to 2.1 GHz is designed with 0.18 μm SiGe BiCMOS technology, which will be used in GSM, TD-SCDMA, and RFID systems. The proposed power amplifier adopted broadband matching, compensated matching, and negative feedback technique. The simulation results show that under a supply voltage of 3.3 V, the power amplifier demonstrates 35 dB power gain, 30 dBm output power, and higher than 25% power added efficiency. Gain ripple is lower than 2.5 dB and the input VSWR is better than 1.8:1 over the whole frequency band. The layout size is 2.6 mm × 1.5 mm.
