... Introduction Introduction 1 In the STV6111 satellite tuner, on the RF input, there is a variable gain, low-noise amplifier (VGLNA). The RF gain is monitored by an automatic gain control (AGC) circuit to ensure an optimal signal level for the two mixers. Each mixer, which down-converts the signal to the baseband, is followed by an AGC-controlled VGA, a low-pass filter and a second VGA. ...
