Abstract
The gain characteristics of certain stages of a tuner circuit are selected to be proportional, but opposite, to selected other stages such that the overall gain of the tuner remains constant over a wide temperature range. In one embodiment, the gain of the IF stage has a temperature slope opposite to the temperature slope of the input RF stage thereby avoiding the use of AGC circuitry.
