2-way RX splitter

Posted date: March 09, 2019in: Equipment

The splitter or combiner is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads. Like all passive splitters and combiners, this device is less than ideal. Isolation is maximum only when at least one port are properly terminated. In this case isolation between the two splitted/combinated ports is maximum when the main port is properly terminated. This HW is designed only for RX line. There are some more high current and voltage protections on all ports. Both impedances 50 or 75 Ohm can be selected by the jumper.

Main functions:
