47-1000MHz 2 Output CATV Line Extender Amplifier With ATC For
Bidirectional Network
Features
The trunk amplifier enlarges, controls and assigns the up and down
signals on the trunk and branch wire.
1, Power supply: Power supply owns the input protection circuit and
suppresses the network out of the influence of the instant power
supply surge.
2,JZD trunk amplifier: The combination of front adjusting equalizer
and constant equalizer and the using of back equalizer which not
only improve the system index and also transmit the long distant
signal efficiently, that will be suitable the characteristic of the
system if used in conjunction with it .
3, Reasonable ATC temperature compensation controls the circuit.
4, There has card surge discharger, coordinating current absorption
point, double lightening-proof measure
5, Inside branch and assignment of the signal make the outside
assignment distributor to minimum.
6, JZD reverse subassembly parts: Modularized reverse return
transmission enlargement parts provide the slope and gain control.
Card two-way wave filter can realize the different frequency
partition. Suitable frequency range to 5~30/42/65MHZ can satisfy
the choice of different system.
7, Inside accuracy reverse input and output test port (-20dB) or
signal input point are convenient to the testing and debugging of
the two-way network.
