3-way active splitter in BOX
This active splitter allows you to split one antenna into multiple RX. The splitter can also be used to split a reference frequency, for example 10MHz. The outputs have high isolation and minimal difference in splitting. The input includes a diode limiter and the preamp gain can be varied by an output attenuator.

This 3-way active splitter in BOX is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads. This is active splitter version where you can switch ON high IP, low noise preamplifier and eliminate insertion loss of the splitter. Gain can be set as you need by the Variable ATT at PCB. 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 je jumper.
