2N5638 JFET Chopper Description

2N5638 is an N-channel JFET with a wide range of applications. It runs in depletion mode and must be turned off with reverse biasing. It is intended for mid to high-frequency ranges. It also offers a high gain for broad frequencies and is useful in VHF/UHF-based systems. It is a low-noise small-signal device capable of quick switching, signal amplification, and mixing.
