Abstract

A design of Ku-band(11.7~12.20Hz) monolithic microwave integrated circuit(MMIC) low noise block(LNB) downconverter using self oscillating mixer (SOM) for direct broadcast satellite(DBS) application is presented The proposed LNB downconverter is composed of low noise amplifier(LNA), image reject filter(IRF), SOM , low pass filter(LPF). The conversion gain is 30dB , VSn is less than 1.7: 1 and overall noise figure is less than 1.2dB.
