PRO-DDPF E-GSM-R
Dual Duplex Protection Filter for E-GSM-R
Description
- Low insertion loss.
- High level of rejection close to the passband.
- Good rejection of out of band spurious signals.
- Reduces interference from public mobile networks.
- Protect the E-GSM-R Cab radios from blocking problems.
- European International Union of Railways (UIC) has reported a high number of E-GSM-R network problems caused by interference from strong public mobile networks signals (E-GSM-R, UMTS and LTE). The reported cases show that the interference from the public mobile network transmitters effects E-GSM-R equipment installed in railway trains e.g. receiver desensitization, receiver blocking and receiver overload.
- The number of interferences is expected to increase in future, due to the planned deployment of E-GSM-R in Europe and the general growth of public mobile networks.
- Amphenol Procom has developed a dual duplex protection filter for the E-GSM-R band (PRO-DDPF E-GSM-R) that attenuates the interference from public mobile networks and reduces the blocking problems to non-critical levels.
- The Dual Duplex Proctection Filter is devolped using dielectric resonator technology in order to achieve a low insertion loss and a high level of rejection close to the passband.
