CATV Amplifier
The trunk amplifier enlarges, controls and assigns the up and down signals on the trunk and branch wire.
Power supply: Power supply owns the input protection circuit and suppresses the network out of the influence of the instant power supply surge.
JZE trunk amplifier: Front and back combined using can transmit the long distant signal efficiently. That will be more suitable for the characteristic of the system if used in conjunction with it.
There has card surge discharger, coordinating current absorption point, double lightening-proof measure.
Inside branch and assignment of the signal make the outside assignment distributor to minimum,which save the cost and increase the reliability.
JZE reverse subassembly parts: Choosing and setting reverse amplifier module which can transmit the reverse signal and provide the front , back slope and gain control. Card two-way wave filter can realize the partition of different frequency. Suitable frequency is from 5~30/42/65MHZ, which can satisfy the choice of different system.
