本文介绍了一种宽带毫米波有源巴伦,它由CB/CE输入和全差分第二级组成。在54- 59 GHz通带内,幅相误差分别为0.7±0.5dB和±5°。测量|S <inf>n</inf>|在50- 65 GHz范围内&lt;− 18 dB,使用共源共栅实现优于39 dB的总体反向隔离。在130 nm SiGe-BiCMOS上实现了0.2×<sup>0.19mm2</sup>巴伦,在2 V电源下功耗为10.4mW。
A wideband mm-wave active balun consisting of a CB/CE input and fully-differential second stage is described. In the 54–59GHz passband, measured amplitude and phase errors are 0.7±0.5dB and ±5°, respectively. Measured |S<inf>n</inf>| is <−18dB from 50–65GHz, and cascoding is used to realize better than 39dB reverse isolation overall. The 0.2×0.19mm<sup>2</sup> balun is implemented in 130nm SiGe-BiCMOS, and consumes 10.4mW from a 2V supply.
