Abstract :
This paper presents W-band microstrip shunt switches on quartz substrates. The -20 dB isolation bandwidth of the switches is limited to around 10% due to the /spl lambda//sub g//4 radial stubs used, with an insertion loss of -0.2 to -0.5 dB. The microstrip switches are used in a switched-line phase shifter and a reflect-line phase shifter at W-band frequencies, and resulted in good performance over a 5-10% bandwidth.
