PHY-TETRA-4-FME-…
TETRA combiner with VSWR adaption/adjustment network
Description
- Combiner for coupling of four TETRA mobile transceivers on one common antenna.
- Factory-adjusted to either 380 – 410 MHz or 400 – 430 MHz.
- Compact dimensions – especially suitable for mobile applications.
- FME-connectors for direct connection of FME-cable without extra adapter.
- For parallel operation of four two-way communication radios (transceivers) where highest possible decoupling (isolation) is necessary.
- Integrated VSWR adjustment network for optimization of isolation in the frequency range of 380 – 410 MHz or 400 – 430 MHz. Via the adjustment network the effective VSWR of the antenna can be optimized and consequently the isolation between the ports of the combiner clearly improved.
- High isolation obtainable: Up to 60 dB (Dependent on the VSWR of the connected antenna).
- The adjustment of the VSWR adjustment network takes place via built-in variable capacitors.
- Max. TETRA transmitter power 4 x 5 W.
- Also usable as equal power divider for max. 20 W.
- Very small ripple over the total frequency range.
