QM-SW-4S DC-3.5G RF Switch SP4T Switch with High Isolation and Low Insertion Loss

QM-SW-4S DC-3.5G RF Switch SP4T Switch with High Isolation and Low Insertion Loss

Description:
Microwave switch, also known as radio frequency switch, realizes the function of controlling the conversion of microwave signal channels. This module adopts SP4T 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. Thanks to CNC housing, it is easy to install. With stable and reliable performance, the module covers DC-3.5GHz, and can be used in typical frequency points such as 433M, 486M, 915M, 1575M, 2.4G, etc.
