HERMETICALLY SEALED TRANSFER SWITCH WITH SMA CONNECTORS FROM DOW-KEY MICROWAVE

Ventura, California – December, 2002

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’s newest product, High Power Switch (P/N 411NTV-2308), is a hermetically sealed transfer switch with SMA connectors that performs from DC to 1 GHz with upgrade capability up to 18 GHz. DC characteristics include 26-32 VDC (28 VDC nominal) with 140 mA typical @ 25ºC operation. Equipped with a failsafe actuator, this switch has an operating speed of 20 ms (max) but can be upgraded to switch in less than 5 ms.

Designed to operate in the extremely harsh environment typical of military applications, the switch can also be utilized as a building block for high power switchable networks.

 

Specifications:

Frequency Range (GHz) DC – 1
VSWR (max.) 1.15:1
Insertion Loss (dB Max.) 0.2 dB
Isolation (dB Min.) 85 dB
Return Loss (dB Max.) 200 WCW @ 400 MHz

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