Abstract :
A fully integrated satellite tuner is described that can receive all channels from European satellites transmitted using PAL, SECAM, or D2MAC. The main receiving unit is connected to two antenna amplifiers that separate the left and right signal polarizations. Two low noise amplifiers are installed at the parabolic antenna, and establish a low-loss match for different lengths of antenna cable. The receiver´s input is such that, after low-pass filtering, a two-stage wideband RF amplifier is connected to a two-pole varicap tuned stripline filter, covering 950-1750 MHz and having a 3-dB bandwidth of only 70 MHz. Mixer and filtering stages connect the receiver to an FM quadrature demodulator. Layout of the chassis, audio, and video performance data are listed
