Transfer Switches

Cobham Signal & Control Solutions - Transfer Switches

The XF series of PIN diode transfer switches span the frequency range of 10MHz to 18GHz. The switches are available in a wide variety of standard frequency ranges from cost-effective narrowband to high-performance broadband.

Each switch incorporates a TTL-compatible driver for convenient system integration and operates from +5V and -12V to -18V DC power supplies. All switches incorporate DC blocks at the RF ports. Standard screened switches incorporate epoxy sealed lids and undergo a stringent yet cost effective screening cycle.

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

Applications:

  • EW Systems
  • Communications Systems
  • Diversity Control
  • Test Equipment
  • Electronic Simulators
