Design method and manufacturing monolithic microwave integrated circuit switches on GaAs рНЕМТ

This paper proposes a new synthesis method for design of solid-state microwave switches. The synthesis method based on the design of a prototype low-pass filter. By implementing successive frequency transformations and circuit conversions, a switch topology obtained. The effectiveness of the method is demonstrated by manufacturing a monolithic GaAs рНЕМТ SPDT switch of C-band.
