Ventura, California – May, 2005

Dow-Key Microwave (a subsidiary of Dover Corp., NYSE:DOV), an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, Switch Matrices, Integrated Modular Assemblies, and related passive components, is introducing its newest product….a new generation of Multi-position Switches designed for the ATE Market.

Dow-Key Microwave is targeting this family of Multi-position Switches toward ATE Applications. This group of internally terminated switches consists of SP6T, SP8T, and SP12T models. As an option, the unit”s internal terminations can be replaced with standard SMA connectors. This alternative would allow the use of high power external terminations or access to the 6, 8, or 12 pathways, permitting insertion of test equipment or a redundant device.

DC characteristics include 22-26 VDC (24 VDC nominal, operating current is 250 mA typical @ 20ºC). Equipped with a latching actuator, this device switches in 20 ms (max).

These switches provide excellent insertion loss repeatability (± 0.05 dB) and phase repeatability (±0.6°) to 9 GHz. Operating frequency range is DC to 26.5 GHz. The control circuitry includes internal self cut-off and BCD decoder (TTL driver optional). The switches are also available with CANBUS interface.

Dow-Key”s product line ranges from single-pole single-throw to single-pole 14-throw, Transfer, Inline, Waveguide switches as well as Switch Matrices, and Integrated Modular Switch Assemblies.
