Ka-Band Calibration-Free High Image-Rejection Up/Down Mixers With 117% Fractional IF Bandwidth for SATCOM Applications

Ka-Band Calibration-Free High Image-Rejection Up/Down Mixers With 117% Fractional IF Bandwidth for SATCOM Applications

This paper presents two Ka-band calibration-free up/down mixers, each with high image rejection ratio (IRR) for a wide band of IF frequencies covering the satellite modem frequency range (0.95-2.15 GHz). To achieve broadband IRR > 30 dBc, a 3-stage castle-wall polyphase filter (PPF) is used a...
