Extending amplifier
Detailed Product Description
Product feature
Bandwidth 750MHz or 862MHz, bi-directional transmission.
Adopting GaAs or power double module output stage with high output level and low distortion feature.
Components are modularized design, easy to maintain and upgrade.
Two-ways separate return channel, changeable return channel attenuator, output level could be controlled flexibly.
High-grade switch power supply with +24V1.5V current, 40~90VAC voltage ensuring the security and reliable operation.
With automatic gain control function to make sure there is stable output level within the certain range. Technical index
