SUMMARY VA-860G system Amplifier with two way high gain amplify
power drive
multi-ports output broadband bi-
directional(bridge)Amplifier, compensate cable transmitting for RF-signal loss in CATV system. VA-860G serial broadband bi-directional amplify is two grade module amply design: low noise module (wideband hybrid)amplifier in preposition. Use plug-in design improve non-linear index of output signal. Return path
design with input output signal -20dB test point and input
output signal level adjustment function. This product
have high work efficient and stable work capability, and widely practicability.
