  • Phase and amplitude signal sensing circuit for radio frequency (RF) transmitters
    Patent number: 10305610
    Abstract: A radio frequency (RF) transmitter for self-sensing power and phase of an RF signal is provided. A local oscillator (LO) is configured to generate a LO signal. A power amplifier is configured to generate the RF signal from the LO signal, wherein the LO and RF signals are periodic signals sharing a waveform and a frequency. An IQ de-modulator is configured to down convert the LO signal and the RF signal into an in-phase (I) signal and a quadrature (Q) signal, wherein direct current (DC) voltages respectively of the I and Q signals define power and phase of the RF signal. A method for self-sensing power and/or phase of an RF signal, and a radar system within which the RF transmitter is arranged, are also provided.
    Type: Grant
