A C-Band satellite receiver
Abstract
The design concept of a 24-channel C-band receiver for satellite TV signals is presented. The system comprises a low-noise amplifier, a 3.7-4.2-GHz/450-910-MHz block down converter, the receiver proper (a modified analog UNF tuner at IF = 45 MHz and a digital channel selector), and an RF modulator providing video and audio on channels 3 or 4. The operation of the receiver is described and illustrated with block diagrams and tables of specifications. A prototype receiver has been found to give good video quality and definition with clear 20-20,000-Hz audio when used with a 4-ft dish antenna.
