3-channel Square Cavity Combiner with extended Tx-Tx isolation for the UHF frequency range 740 - 870 MHz

Beschreibung

  • The Amphenol Procom series of Square Cavity Combiners have been designed to help identify the optimum solution for combining several transmitters into one antenna.
  • The Square Cavity Combiners are moreover designed by the square or rectangular shape of the cavities themselves to fill in a minimum of rack space, compared to other similar round types of combiners.
  • The Tx Combiners are highly used in Public Safety radio systems in US used by e.g. policeforces, the firebrigates and the ambulance services.
  • The Public Safety networks as FirstNet and P25 are allocated e.g. in the frequency spectrum 758 - 776 MHz / 788 - 806 MHz and in the range 806 - 824 MHz /
    851 - 869 MHz
  • Beside the utilization in Public Safety networks the Tx-combiners are also highly used in commercial/private wireless radio neworks in the 776 - 788 MHz area.
    Here the Tx-combiners are securing isolating the noise from its own transmitters, so they will not interfere on its own radio receivers and will not interfere other adjacent PMR or Public Safety radio networks
  • The Square Cavity Combiner can accomodate high power upto max. 150 W CW per
    Tx-channel
  • To acheive the very best and sufficient Tx-Tx isolation at high Tx power levels over the Frequency range 740 - 870 MHz range, 2 pcs Broad Banded Dual Isolators are fitted as standard for each channel.
  • The cavities included in the combiner can, due to he use of broad banded isolators, be tuned in the whole band 758 - 776 MHz with just the related one cable kit.
  • Please, when ordering, specify the frequencies for tuning the Tx channels
