Microwave switch, also known as radio frequency switch, realizes the function of controlling microwave signal channel conversion. This module adopts SP4T single-pole four-throw mode to realize the switching of four-way signals. Because of its low insertion loss, wide frequency band, and high isolation, it is widely used In communication system equipment, CNC structures are used Shell, easy to install, stable and reliable performance.
