Ventura, California – July, 2003

Dow-Key Microwave (a subsidiary of Dover Corp., NYSE:DOV), is an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, switch matrices, integrated modular assemblies, and related passive components. Dow-Key is proud to be the first microwave company to bring to market a 3-volt actuated MEMS Switch. This switch performs up to 6 GHz with a total DC power consumption at less than 3 mW. The maximum input RF peak power is 3W, and the upper limit for average power is 2W.

The DKM812-3 is a reflective RF switch that utilizes breakthrough MEMS technology to provide extremely low insertion loss and high linearity (IP3>65 dBm) in a compact package. The switch is housed in a (7 x 7 1.5 mm) JEDEC MO-220 package while the internal switching device is housed in a hermetic CSP package.

This high reliability switch is ideally suited for ATE, instrumentation, LANs, GPS receivers, wireless handsets, reconfigurable antennas, and other applications where low loss and linearity are critical.

Samples are available immediately, and qualified will be ready by November
