3. A satellite communication receiver is designed to receive a transmission at 136.5 MHz. The receiver uses two heterodyne operations (dual-conversion receiver) with intermediate frequencies of 25 MHz Texas A&M University-Kingsville, Electrical Engineering and Computer Science Department & 12 MHz, as shown below. The first local oscillator is designed to operate above the incoming carrier frequency, and the second local oscillator is to operate below the first intermediate frequency Mixer # 1 Mixer #2 Output RF X Filter & IF,...
