High Power Switches

Cobham Signal & Control Solutions - High Power Switches

The Cobham Signal & Control Solutions series of High Power T/R diode switches span the frequency range of 5MHz to 6GHz and are available with absorptive output on the RX port and reflective port on the TX side.

The switches are available in a wide variety of standard frequency ranges. Each switch incorporates a TTL-compatible driver for convenient system integration and operates from +5V to +12v and -50V to -150V DC power supplies (depending on RF power requirements). All switches incorporate DC blocks at the RF ports.

Some switches are also available with hermetic seal and high-rel screening for military and aerospace applications.
