The purpose of this circuit is to limit noise peaks on a radio receiver. The circuit is from an 80's documentation. The diode is commonly used and the circuit is applied to a receiver IF stage.
Here we show an oscillator that uses an LC network. The upper limit depends on the power-supply...
This interesting FET-tester circuit was obtained from an old American documentation. The bipolar...
