  • POWER DETECTOR
    Publication number: 20230258699
    Abstract: In certain aspects, a method is provided for measuring power using a resistive element coupled between a power amplifier and an antenna. The method includes squaring a voltage from a first terminal of the resistive element to obtain a first signal, squaring a voltage from a second terminal of the resistive element to obtain a second signal, and generating a measurement signal based on a difference between the first signal and the second signal. In some implementations, the resistive element is implemented with a power switch.

  • Regenerative frequency doubler
    Patent number: 11239797
    Abstract: A frequency doubler is provided that filters an input signal to form I and Q components responsive to a tuning signal. A single sideband mixer mixes the I and Q components with I and Q components of a local oscillator signal to form an output signal having a frequency of twice the frequency of the input signal.
