SYSTEM AND METHOD FOR GENERATING LOCAL OSCILLATOR (LO) SIGNALS FOR A QUADRATURE MIXER

摘要

Orthogonal system for generating an LO (local oscillator) signal to the mixer is configured to supply a reference frequency signal oscillator, configured to divide the reference frequency signal to the three offset phase signal at least one frequency divider, two from three offset phase signal nominal 90 second the first summing circuit, and at least two amplitude compensation offset 90 configured to generate a phase offset signal, and a second summing circuit configured to generate a phase quadrature signals. ; Quadrature mixer, a transceiver, LO signal, subharmonic, harmonic modulation
