What Is a Microwave Diode?
A microwave diode is a specialized semiconductor device designed to handle radio waves within the microwave frequency band, spanning a broad range of frequencies.
These diodes play a pivotal role across diverse fields, including microwave communication, radar systems, and medical instrumentation. Operating on the principle of PN junctions, microwave diodes facilitate functions such as rectification, detection, frequency conversion, and current amplification upon the application of voltage to the semiconductor structure.
Their applications extend to microwave communication transceivers, radar systems for both transmission and reception, medical devices employing microwave therapy, collision avoidance systems in automotive technology, microwave heating processes, and industrial equipment for inspection purposes. Structurally, microwave diodes typically comprise a semiconductor chip featuring PN junctions, interconnected electrodes, and protective packaging.
