Ventura, California – July, 2001 — Dow-Key Microwave (a subsidiary of Dover Corp . I NYS E: DOV), is an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, Switch Matrices, Integrated Modular Assemblies. and related passive components. Its Most recent product, a CANBus controlled SP12T Smart Switch), offers internal 50 Ω termination and performs up to 2GHz Operating frequency can be upgraded to 18 GHz. DC characteristics include 22-26 VDC (24 VDC nominal operating current is 500 mA typical @ 20ºC). The switch (P/N 5CIH480823A-2) is equipped with an actuator, providing a latching mode of operation.

This Smart Multi-position Switch targets the ATE market and provides the first available SP12T solution with serial CANBus interface for all applications chat require high repeatability of insertion loss and phase. Typical insertion loss and insertion phase repeatability is ±0.03 dB and =.32 respectively.

CANBus architecture allows for an easy integration of large switching systems that could utilize over 150 switches in one network, reducing complex programming and integration time of an overall system.
