75 Ohm / 50 Ohm RF Matix Systems Features: This series of solid state switching models are either offered with 75 ohm or 50 ohm impedance and are ideal to be used in the broadcasting industry for receiving and transmitting video signals. These systems are available with non-blocking full fan-out (any input connected to any output simultaneously) capability and are offered in IFband (20-200 MHz), L-band (950-2250 MHz), and broad band (50-2150 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 offered upon request. The standard inputs/outputs configurations start at 8x8 and goes all the way up 128x128. Other configurations may be available upon contacting Dow-Key. The chassis size of these systems range from 2U/3U for the 8x8 up to 18U for the 64x64, and beyond 18U for larger systems.
