A fully integrated down-converter for Ka-band VSAT satellite reception

A fully integrated Ka-band down-converter IC for VSAT applications will be demonstrated. The High-Band (21.422.0GHz) and the Low-Band (19.2-20.2GHz) are simultaneously down converted into the L-band and independently accessible by two users. The SSB-NF is better than 8dB at a conversion gain of 25dB (20dB) for the Low-Band (High-Band). The integrated PLL achieves a state-of-the-art integrated phase noise of 1.2 degrees rms. The total solution consumes a maximum of 548mW.
