RF Amplifier This amplifier provides a maximum gain of 29 dB. The gain is programmed by applying a DC voltage (from 0 to 3 V) to the AGC pin, providing 27 dB of range. Downconversion Mixer This double balanced mixer has 12 dB of conversion gain. The outputs of the mixer are both open drain and require pull-up inductors to VDD.
Video Amplifier This amplifier provides a maximum gain of 55 dB. The gain is programmed by applying a DC voltage (from 0 to 3 V) to the AGC pin, providing 28 dB of range. The outputs of the video amp are both open drain and require pull-up inductors to VDD.
Note: 1. The RF amplifier and video amplifier are controlled by a single AGC so the overall dynamic range is the sum of the RF amplifier range and the video amplifier range.
