The HVM189STL-E is a PIN diode from the * series, designed for RF switching, attenuator, and limiter circuits where low capacitance at reverse bias and low series resistance at forward bias are required. PIN diodes are used in antenna switch matrices, variable attenuators, and RF front-end protection — common in telecom infrastructure, test equipment, and broadcast transmitters.
