Working Principles

The AS1158-T is a bipolar junction transistor (BJT) that operates based on the principles of amplification. It consists of three layers of semiconductor material - the emitter, base, and collector. By applying a small input current to the base-emitter junction, a larger output current flows through the collector-emitter junction. This amplification process allows the AS1158-T to boost weak signals while maintaining signal integrity.
