Internal Circuit

Description

IF amplifier balanced inputs.

Should be decoupled with a ≥ 0.01µF capacitor.

3

IF AGC filter pin.

The filter capacitor should be 1µF. A capacitor with good tan

δ temperature characteristics should be used, such as an

ALSi capacitor.

If power supply ripple is high, ripple on the detector output

can be reduced by using the following circuit.
