Abstract
This disclosure provide various techniques for improving the quality of a signal. By integrating phase-shifting circuitry with a transmit/receive (T/R) switch, insertion loss may be reduced while decreasing space consumed on an integrated circuit or printed circuit board. In particular, embodiments disclosed herein include a transmitter and a receiver, each including one or more differential amplifiers coupled to a first inductor, and a switching network coupled to a second inductor and one or more phase-shifting circuitries. A differential interface of the differential amplifiers may enable integration of a stage of the phase shifter (e.g., a 180 degree stage) with the T/R switch, such that a single circuit may operate as the phase shifter and the T/R switch. This implementation may reduce the number of T/R switches and phase shifter stages in the phased array system, reducing the overall insertion loss experienced by the phased array system.
