Low power and small sized Ku-band MMIC low noise block downconverter design using InGaP/GaAs HBT process

In this paper, low noise block downconverter (LNB) is designed for Ku-band satellite communication system using commercially available 6 inch InGaP/GaAs HBT high linear process. Designed MMIC is composed of low noise amplifier, double balance mixer, and IF amplifier with a total chip area of 2.6/spl times/1.1 mm/sup 2/. Designed MMIC yields conversion gain of over 37.5 dB, noise figure of less than 14 dB, ripple of 3 dB, and output-referred P/sub 1dB/(1 dB compression power) of 2.5 dBm with total power dissipation of 3 V, 50 mA.
