The 4-way active signal splitter is designed to be used to split a signal in the 100kHz to 100MHz range to several 50ohms ports without degrading the signal.

Typical uses are:

• Sharing an antenna to several receivers.

• Sharing a 10MHz reference signal to several instruments.

• Instrumentation amplifier for high impedance signals to feed to 50ohms inputs (Jumper H1 is off) 

​

The board have four outputs and if more outputs are needed several units can be connected together to give the wanted number of outputs.

​​​

The input impedance can be changed from 50ohm to high impedance (>100kohm) by means of the jumper H1.

The board needs a DC power source in the range of 12 to 25V to work.

The voltage gain is 1 regardless of the number of output used.

The amplifiers used gives low distortion and high IP3 for signals in the 100kHz to 30MHz range.

The board can be used up to 100Mz with reduced IP3 performance above 30MHz.
