VENTURA, Calif. (August 24, 2009) – Dow-Key Microwave is pleased to offer 75-ohm switching systems as a great addition to their 50-ohm matrix product line. These systems are ideal to be used in the broadcasting industry for receiving and transmitting 75-ohm signals, but are equally valued to be used with any other 75-ohm application.

Currently, non-blocking full fan-out (any input connected to any output simultaneously) solid state switching systems are available with operating frequencies in IF-band (20-200 MHz) and in L-band (950-2150 MHz). Generally each system is equipped with low noise amplifiers (with high dynamic range,) local control using LCD and pushbutton keypad, and LAN (Ethernet) interface for remote control. Options such as redundant power supply and other remote interfaces such as IEEE-488 (GPIB), RS-232, RS-485, and RS-422, are also offered upon request.

The standard inputs/outputs configurations of Dow-Key’s 75-ohm matrices start at 8×8 and goes all the way up 128×128. Other configurations may be available upon contacting Dow-Key.  Furthermore, all unused input paths are internally terminated for the units operating in the IF-band and the chassis size of these systems range from 2U/3U for the 8×8 up to 18U for the 64×64, and beyond 18U for larger systems.

For more information on other systems contact Dow-Key directly at dkm@dowkey.com or (800) 266-3695, or download below data sheet.
