提出了一种电平衡放大器，该放大器采用部分耗尽RF绝缘体上硅CMOS工艺，实现了最先进的线性度和插入损耗（IL）性能。单端配置避免了差分低噪声放大器拓扑所面临的共模隔离问题。高度线性的开关电容器允许在1.9至2.2 GHz范围内对电压驻波比<1.5：1的天线进行阻抗平衡。在高发射机（TX）功率（最大+30.5 dBm）下，可实现+70 dBm的输入参考三阶交调点。TX IL <3.7 dB，接收机IL <3.9 dB。
An electrical-balance duplexer achieving the state-of-the-art linearity and insertion loss (IL) performance is presented, enabled by a partially depleted RF silicon-on-insulator CMOS technology. A single-ended configuration avoids the common-mode isolation problem suffered by topologies with a differential low-noise amplifier. Highly linear switched capacitors allow for impedance balancing to antennas with <;1.5:1 voltage standing wave ratio from 1.9 to 2.2 GHz. +70-dBm input-referred third-order intercept point is achieved under high transmitter (TX) power (+30.5 dBm max.). TX IL is <;3.7 dB, and receiver IL is <;3.9 dB.
