PRO-PHY150-2

2-Channel Hybrid Ring Combiner for 150 MHz Transmitters

  • Combining two transmitters or receivers on the same antenna.
  • Better utilization of good antenna position.
  • Two antennas on the same transmitter or receiver.

DESCRIPTION

  • Combining two signal generators.
  • The only combining option with very small TX-TX frequency spacing.
  • 30 W load supplied (other loads or no load as option).

*The isolation between the TX ports is directly dependent on the terminating SWR on the antenna port. With an antenna load SWR = 1.5, the isolation between the two TX ports will be reduced to 20 dB @ 3 MHz bandwidth.

**The SWR of the load’s should be < 1.1! The load should be able to dissipate 1/2 of the total input power.

E.g.: With 50 W input in total for the two channels, the load should be able to dissipate 50 W x 1/2 = 25 W.
