Usage Scenario: 
The device is intended to be used in the components of radio equipment, as a part of an amplifier or transceiver, or as a separate device that performs the function of matching the output impedance of amplifier (PA) with the feeder. This device and the similar 2x5 group The relay is different, which allows it (with the maximum configuration) to work effectively in a wide frequency band, overlapping the radio HF band from 1.8MHz to 50MHz.
