A Fully Integrated Ka-Band VSAT Down-Converter

A fully integrated Ka-band down-converter for VSAT applications will be demonstrated. The high-band (21.4-22.0 GHz) and the low-band (19.2-20.2 GHz) are simultaneously down converted to the L-band (950-2150 MHz) and independently accessible by two users. The SSB-NF is better than 8 dB at a conversion gain of 25 dB (20 dB) for the low-band (high-band). The integrated PLL achieves a state-of-the-art integrated phase noise of 1.2° rms. The total solution consumes 548 mW.
