Example TX-TX isolation curves
1.5:1 VSWR antenna matched at 425 MHz
2.0:1 VSWR antenna matched at 425 MHz
PRO-PHY450-4/380-470/VSWR
4-Channel Broadband Hybrid Combiner for the frequency range TETRA380 MHz & PMR/LTE 450 MHz including antenna tuner for maximum RF matching
Description
- Can combine up to four transceivers on one common antenna where the antenna is not well 50 Ω matched
- By tuning the RF-matching network to the antenna, a good Tx-Tx isolation is maintained..
- Broadband, working in all the frequency range 380-470 MHz, without compromise the Tx-Tx isolation
- As standard the hybrid is supplied with 30 W loads.
- Other loads for higher input power are available on request.
