A 220–320 GHz Single-Pole Single-Throw Switch
2016 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)(2016)
摘要
This paper presents a single-pole single-throw (SPST) switch operating over the entire WR-3 band. The SPST switch is composed of two shunt transistors and transmission lines in between to resonate the off capacitance of the transistors. The switch is implemented using a 250-nm InP DHBT technology. The measured insertion loss and isolation are no more than 2.9 dB and 13.1 dB, respectively, from 220 to 320 GHz. The return loss is better than 10.2 dB over the same bandwidth.
