Description

The PCB for 2-way small splitter - it 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 high current and voltage protections on all ports. Both impedances 50 or 75 Ohm can be selected by the jumper.


Using

  • Antenna splitter
  • RX signal divider
  • One antenna, two RX

Main functions

  • Broadband: 0.1 MHz to 60 MHz
  • Splitter or Combiner
  • Low loss
  • Protections - high voltage / current
  • 50 / 75 Ohm impedance - easy jumper switch
  • Electrostatic protection by neon lamps
  • High power protection
  • ONLY PCB

Parameters

  • Impedance 50 or 75 Ohm
  • Insert loss: around 0.5 dB
  • Split 3 dB, together with IL around 3.5 dB
  • Isolation more than 30 dB, 160-15m more than 40 dB
  • SWR on splitted ports better than 1:1,1 on HF, resp. 1:1,19 on 6m
  • SWR on main port around 1:1,3 on HF, resp. 1:1,4 on 6m
  • PCB size 50x50.4 mm
  • Designed for SMA connectors
