A 12.2--19.1 GHz High-Selectivity CMOS Power Amplifier Chip With Two-Stage Transformer-Based Filtering Matching Network
Xiaopan Chen, Yongle Wu, Zhuoyin Chen, Shuchen Zhen et autres
This letter presents a novel integrated broadband filtering power amplifier (FPA) with a two-stage transformer-based bandpass matching network. The proposed filtering input matching network (FIMN) is composed of a magnetically and capacitively coupled resonator (MCCR) and a cascaded matching balun. The MCCR …
