RF Engineers , WHY- WHY - WHY Analysis ❓ Why Limiters are made up of Schottky Diode ? Ans : 1) Fast switching Why it switches fast ? Because of low junction capacitance. Why low junction capacitance exists ? Because of the small depletion region formed by the metal-semiconductor junction . 2) Low forward voltage drop - Helps faster current conduction and less signal distortion . Why low forward voltage drop? Because of metal semiconductor junction. 3) Clamping action ? Why clamping action happens ? Because of the barrier potential and reverse breakdown voltage . Now , Configuration : Schottky diodes are connected in parallel with the input signal path. When the input signal voltage exceeds the forward or reverse clamping voltage of the diode, the diode starts conducting, shunting the excess voltage to ground or a load, effectively limiting the output voltage to the desired level. Thus performing the limiting action . -‐-----------‐‐-----------‐------------------------------------------ Learning Everyday!😊 P.S.
