A Low Power CMOS Full-Band UWB Power Amplifier Using Wideband RLC Matching Method

This paper presents the design and implementation of a power amplifier for full-band UWB communication system by TSMC CMOS 0.18um technology. We use common source topology with an improved wideband RLC filter method and multilevel RLC matching method to achieve the wideband input/output matching and broadband power gain requirements. In order to increase the bandwidth, we also use both the cascade and cascade stage to increase the gain and gain flatness. Die-on-PCB measurements has shown this PA provides an average power gain of 10dB which from 3.1GHz-9GHz, average Pout_ldB of 0dBm in full-band(3.1GHz-10.6GHz), along with the power consumption of 25.2mW.
