Description

The system meet the requirements of 450MHz wireless train dispatching system, adapts to wireless communication system with different frequency single duplex and same frequency simplex, and provides 2M transparent signal transmission channel. This system has the function of local detection and remote monitoring of communication power supply (equipped with corresponding terminal software and hardware). It can detect input voltage, output voltage and current, detect battery voltage and current, and alarm for power unit failure, external outage, battery undervoltage and so on. Key components of this system: the power module, the optical module and the amplifier module have redundant configuration. The integrated dual fiber optical module is used and the main fiber-optical can be automatically switched. It has the alarm function for the main module switch. This system can provide data transmission channels for external devices such as external communication power and environmental monitor. Specification -Work frequency range: uplink 457 ~ 459MHz; downlink different frequency 467 ~ 469MHz; downlink same frequency 457 ~ 459MHz; -Communication: different frequency duplex; different frequency simplex; same frequency simplex -Maximum output power: uplink: -10±2dBm; downlink: 37±2dBm -Maximum allowable input level: no damage to the repeater when the input level is 0dBm -The automatic level control (ALC): dB ≥10dB(Pomax±2dBm) -Passband Ripple: ≤2dB -The uplink input noise coefficient:≤5dB -The port voltage SWR: ≤1.4 -Device gain: uplink: 53±2dB, downlink: 55±2dB; The gain adjustment step and step error: step≤1 dB,error≤±1.5dB The gain adjustment range: ≥30dB
