... OUTRefDiv 2.2 Downconverter and Baseband Filtering The L band input from the LNB is fed into the CX24118A either differentially or single-ended. The input signal goes through a low-noise amplification block and is downconverted to a baseband frequency by quadrature downconversion. The output of the downconverter is band limited by a variable bandwidth filter that can be set to 35, 40, 65, or 100 MHz. A ...

... Gain Settings The CX24118A is controlled by a single AGC signal, providing a dynamic range of 90 dB. The gain stages include an LNA (Low Noise Amplifier) and VCA (Voltage Controlled Attenuator), VGA1 (Variable Gain Amplifier 1), VGA2, and a final amplifier. These gain stages are shown in figure 2-1. ...
