TVAmplifier with two way high gain amplifypower drivemulti-ports output broadband bi-directional(bridge)Amplifier, compensate cable transmitting for RF-signal loss in CATV system. VA-860B3 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 inputoutput signal -20dB test point and inputoutput signal level adjustment function. This product have high work efficient and stable work capability, and widely practicability. Features: (1) 1000MHz bidirectional design,(550/750/862MHz). (2) SMD and SMT . (3) Bidirectional filter with plug-in design, 30/42/65MHz. (4) Plug-in equal adjustment. (5) Plug-in slope circuit, improve signal non-linear distortion. (6) ATT and AGC adjust continously (range:0-20dB). (7) Single output can enlarge to two or more than two output. (8) RF output -20dB test point. (9) Power supply: 60V/AC and 220V/AC optional. (10) With ATC(Automatic Temperature Compensation). (11) With over-current protection and lightningproof.
