Product Detailed
1)CATV Weatherproof Line Amplifier with ATC 2)ATT&AGC adjust continously(1-20dB) 3) use SMD&SMT 4)RF output-20dB test point CATV Weatherproof Line Amplifier suitable for CATV network, repair the ATT of cable transmitting and Rfsignal, extend RF signal transmitting. Use modularize, plug-in design, collocate according to customer requirements.VA-860B Serial Bidirectional broadband Amplifier is two grade amplify design; low noise module amplify, use plug-in slope circuit to improve output signal non-linear index. Output signal is -20db test point. Inputoutput signal level adjustment, offer a convenience for network return design and system debugging. With offshoot output or two-way distribution output improves the practicability of the products.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.RF Parameter:
