PRO-PHY450-2/380-410/SWR

2-Channel Hybrid Ring Combiner for TETRA Communication Radios

  • Combiner for coupling of two TETRA transceivers on one common antenna.
  • SWR adjustment network for optimization of SWR in the frequency range of 380 to 410 MHz.
  • High isolation achievable: Up to -50 dB in the centre frequency (dependant on the SWR of the connected antenna).

DESCRIPTION

  • For parallel operation of two two-way communication radios (transceivers) where highest possible decoupling (isolation) is necessary. Via the adjustment network the SWR of the antenna and consequently the isolation between the ports of the combiner can be clearly improved.
  • The adjustment of the SWR adjustment network takes place via built-in variable capacitors.
  • Max. power 2 x 50 W.
  • Very small ripple on the connectors over the total frequency range.
