摘要: A wideband Low Power Single Pole 6-Throw (SP6T) antenna switch has been designed for GSM/DCS/802.11b mobile standards using a newly improved architecture and fabricated pseudomorphic depletion mode 0.18@mm HEMT GaAs process. The exhibits less than 1dB insertion loss isolation performances from up to 53dB at 0.8GHz down 42dB 2.5GHz. circuit DC power consumption is 500@mW in full transmission condition makes it suitable use terminals like phones or PDAs. paper presents simulation results validated by experimental measurements on an IC prototype.
