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.
