Abstract :
A dual-band image-reject mixer is designed for a GPS L1/L2 dual-band receiver with an extension of the conventional Weaver architecture. The quadrature mixer with phase ermr compensation capability in the quadrature LO signal without calibration and tuning is reported. The measurement of the dual-hand image-reject mixer demonstrated 64dB image reject ratio (IMRR).
