1.CATV Distribution Amplifier 2.frequency:45(87)~550 45(87)~750 45(87)~862MHz 3.Outpu:94,98,102 dBuV 4.Gain:20 26 30dB Features

(1) Suitable for trunk amplification and extending amplification in forward CATV system.

(2) Using plug-in module (made by PHILIPS or MOTOROLA) design to make upgrade easy.

(3) Manual gain control and slope control.

(4) Provide two power supply method, centralized (AC30~60V) or individual (AC220V).

(5) Individual input port AC60V power supply.

(6) Waterproof and dustproof design, fast heat dissipation and fine screening characteristic.

(7) Efficient R-transformer or switching power supply for selection.

(8) Plug-in temperature compensator or output beforehand equalizer for selection.
