Ka-band low loss and high power handling GaAs PIN diode MMIC phase shifter for reflected-type phased array systems

This paper describes the design and performances of a GaAs PIN diode and a reflected-type MMIC phase shifter in Ka-band. With optimized geometries and fabrication process, the GaAs PIN diode has shown the highest fmax so far. Excellent performances of MMIC phase shifters have also been obtained.
