NE602 INPUT CIRCUITS

Posted on Feb 5, 2014

A few of the many ways to input a signal into the NE602. Simple untuned methods (a and b) are acceptable. If you need to tune to a specific frequency, you can use an LC resonant circuit with un-grounded trimmer capacitors (c and d) or with grounded variable capacitors (e). You can even use a tuning voltage in connection with a varactor (f).
