SP8T SMA Type RF Switch (0.01-8GHz) Technical Specifications

A射频开关 is a device that controls the switching of radio frequency signals, allowing for the control of signal pathways to select the signal transmission path. This射频开关 features a single-pole eight-throw mode, with external power and control terminals for manual adjustment of the control voltage level.

A low-level signal controls the switching path of the switch, which can also be automatically controlled by program. It is widely used in wireless communication, radar, satellite communication systems, and other fields, featuring a wide working frequency, low insertion loss, high isolation, fast switching speed, and stable performance.
