Hybrid CombinersPRO-PHY450-3/380-470

3-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 three transmitters or receivers to just one antenna.
  • Reduces the required number of antennas.
  • Can also be used with three antennas combining to one transmitter or receiver.
  • As standard the hybrid is supplied with 30 W loads.
  • 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 3 channel hybrid 1/3 of the total input power will be led out to the Ant. port. The rest 2/3 of the total input power will be distributed equal to the 3 loads. E.g. with 3 x 45 W input power, 2/3 = 90 W is accomodated equal in the 3 loads, this means 90W/3 loads = 30 W of power per load.
