ABSTRACT:
A monolithic chip phase shifter consists of a PIN diode which is laterally elongated and shaped into a microstrip-like transmission line. The transmission line has characteristics determined in part by the capacitances associated with the intrinsic layer of the diode. Alternating-current (AC) signals are coupled through the transmission line. Direct-voltage reverse bias, no bias or direct-current forward bias are applied to select the appropriate value of equivalent shunt capacitance of the transmission line to provide the desired phase shift of the AC signals passing therethrough. A high-impedance coupling device couples the bias to the transmission line to prevent leakage of signal to the bias source.
