Abstract
A DC-20-GHz broadband and compact single-pole-quadruple-throw (SPQT) switch for Butler matrix switched beam smart antenna system application has been designed and fabricated on 0.15-μm GaAs pHEMT process. By adopting inductive high impedance transmission lines in series-shunt switch topology, the SPQT switch demonstrates an insertion loss of 1.25-3.53 dB from DC to 20 GHz, and the isolation is higher than 22 dB with a compact chip size of 1.5 mm 2. The measured output 1 dB compression point (OP 1 dB) is 16 dBm at 12 GHz.
