This paper describes a novel quasi-transmission-line variable-reactance circuit that extends the variable-phase range of phase shifters. It consists of a transmission line and two shunt varactors. By appropriately choosing the characteristic impedance and electrical length of the transmission line, the variable-phase range can be significantly increased. Since the proposed circuit can be fabricated by the conventional MESFET process, a phase shifter can be integrated with other functional circuits. This enables fully monolithic integration of RF circuits as a one-chip multi-functional MMIC in radio communication systems. The variable-phase range of the prototype X-band monolithic phase shifter is 208 degrees, which is approximately four times as large as that of conventional one.
