Abstract :
A Ku-band matched embedded-FET phase shifter achieving compact and low insertion loss performance is described. It consists of only a few circuit elements of a series embedded-FET incorporated with a high impedance line and an inductive matching network switched by an SPST switch. A six-bit phase shifter has been developed, consisting of these matched embedded-FET phase shifters for lower bit sections (22.5 °, 11.25 °, 5.625°) and high pass / low pass type phase shifters [1]-[2] for higher bit sections. It has a small size and a low insertion loss.
