Single-Pole, Two-Throw Switches

Cobham Signal & Control Solutions - Single-Pole, Two-Throw Switches

The S2 series of single pole, two throw PIN diode switches span the frequency range of 10MHz to 18GHz and are available with absorptive or reflective inputs. 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 -18VDC 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
  • Antenna Selectors
  • Test Equipment
  • Electronic Simulators
  • Filter Selectors
