Hybrid CombinersPRO-PHY150-5

5-Channel Hybrid Combiner for 150 MHz Transmitters

Description

  • Combining five transmitters or receivers on the same antenna.
  • Better utilization of good antenna position.
  • Five antennas on the same transmitter or receiver.
  • The only combining option with very small Tx-Tx frequency spacing.
  • 30 W load supplied (other loads or no load as option).

* Note

The isolation between the Tx ports is directly dependent on the terminating VSWR on the antenna port.
With an antenna load VSWR = 1.5, the isolation between the two Tx ports will be reduced to 20 dB @ 5 MHz bandwidth.

** Note

The VSWR of the load’s should be < 1.1! Each load should be able to dissipate 4/5 of the input power.
E.g.: With 50 W input, each load should be able to dissipate 50 W x 4/5 = 40 W.
