PRO-PHY450-4/380-470

4-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 four 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.

Additional Information
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 4 channel hybrid 1/4 of the total input power will be led out to the Ant. port. The rest 3/4 of the total input power will be distributed equal to the 4 loads. E.g. with 4 x 40 W input power, 3/4 = 120 W is accomodated equal in the 4 loads, this means 120W/4 loads = 30 W of power per load
