  • Automatic phase shifting control loop
    Patent number: 11742881
    Abstract: A transmitter apparatus and method are disclosed. An RF terminal provides an RF signal. A first antenna transmits a first portion of the RF signal and a second antenna transmits a second portion of the RF signal. Directional couplers generate a first monitoring signal and a second monitoring signal. A power comparison operational amplifier receives the first monitoring signal and the second monitoring signal and generates a power difference signal. A phase control operational amplifier receives the power difference signal and a reference input signal and generates a phase control signal. A phase shifter receives the phase control signal, and based on the phase control signal, phase-shifts the RF signal to direct the RF signal to the first antenna, or phase-shifts the RF signal to direct the RF signal to the second antenna.
