Remote Controllable Switch
The DCR-8 is an eight port RF Switch remotely controllable via USB or Ethernet. The standard broadband switch has an operating frequency of 20 MHz to 18 GHz with an insertion loss of only 4 dB. It also offers excellent port-to-port isolation of minimum 80 dB. The DCR-8 can be custom designed for customer specific bandwidths and switching port applications.

Safe-Guard Switch
The Safe-Guard RF Switch is designed to attenuate the RF transmit signals up to 12 dB or to a reduced power level of 6.3% of the original power. When flammable gases and vapors are present, transmitting at full power greatly increases the likelihood of an explosion. By turning off the DC power to the Safe-Guard RF Switch, the transmit power defaults to the reduced level to maintain minimal communications with the affected site.
