The gain is programmed by applying a DC voltage (from 0 to 3 V) to the AGC pin, providing 27 dB of range. 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. 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. 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. REV.
