Hybrid CombinersPRO-PHY450-2/380-470

2-channel Broadband Hybrid Combiner for the frequency range UHF/LTE 450 MHz

Description

  • New improved design on PCB of high power hybrid combiners.
  • Broadband, working in all the frequency range 380-470 MHz, without compromise the Tx-Tx isolation
  • Used for combining four transmitters or receivers to just one antenna.
  • Can also be used with two antennas combining to one transmitter or receiver.
  • As standard the hybrid is supplied with a 30 W load.
  • Other loads for higher input power are available on request.

Note

* The isolation between the Tx ports is directly dependent on the terminating VSWR on the antenna port. E.g. with a VSWR = 1.5:1 on the ANT. port, the isolation between the Tx ports can be reduced to 20 dB @ in the 380-470 MHz range

**In a 2 channel hybrid 1/2 of the total input power will be led out to the Ant. port. The rest 1/2 of the total input power will be distributed to the 1 load. E.g. with 2 x 30 W input power, 1/2 = 30 W is accomodated to the load, this means the load in this case must be able to accomodate at least 30 W
