A compact 4-bit true-time-delay MEMS phase shifter fabricated on 8-mil GaAs substrate is described. Miniaturization of the phase shifter is achieved using phase shift networks based on semi-lumped LC circuits and a compact SP2T switch configuration. Trade-off in size and loss is performed to achieve a phase shifter with an area of 7 mm/sup 2/ and an average… CONTINUE READING
