General Purpose Dual Port Signal Relay

100 Watts RF power rating. DC - 1300MHz

     
 

Typical applications include:

- By-passing a Converter, Preselector, Preamplifier, Filter, etc. device inserted between antenna and a transceiver or transmitter:

The device is plugged on ports J2 (device input) and J3 (device output). On transmission switchover, via remote control line, the Input and Output RF ports (J2-J3) are by-passed via J1-J4 avoiding being overloaded. Simultaneously ports J2 and J3 are derived to ground adding extra protection.

Other applications let configurations such as: Antenna switching, working with two antennas and one radio, combining two radios and two antennas, protection against electromagnetic pulse (EMP), protection against static discharges (ESD) on stormy weather situations and many more involving RF signal switching. (see below examples)

Default state. (By-passed)

When the General Purpose Dual Port Signal Relay is NOT activated, pins 3 and 4 of the remote control connector are OPEN or the unit is NOT powered the device plugged on Port B and Port C is by-passed and grounded.

Port A and Port R are connected.

 

 

 

 

 


Active state. (NO By-passed)

When the General Purpose Dual Port Signal Relay is powered and pins 3 and 4 of the remote control connector are joined the internal relays switch-over. The device Input (Port B) is connected to Port A and the Device Output (Port C) is connected to the Radio (Port R).
