Introduction

ZJ-LE1G-36APP is a single way high-gain Bi-directional Line Extender amplifier suitable for signal amplification in the HFC system coaxial trunk. The CTB/CSO performance is outstanding with a return loss of 16 dB. frequency of diplex filter is optional. There is also AGC/MGC functions.

Characteristics

1. Gallium arsenide amplifier module used for the forward path. 36dB high gain;

2. Provided with the frequency response adjustment plug- in unit, capable of effectively compensating the convex hull resulting from cable nonlinear attenuation;

3. Internationally advanced passivating treatment and double layer waterproof process are used in the outdoor type aluminum die cast casing, resistant to corrosion and aging, good in heat dissipation, water impermeability and electromagnetic shield;

4.l Forward/Return path input/output level tunable, easy in system debug;

5. Use high quality bidirectional plug-in unit interface , convenient in network update;

6. Highly effective low noise switching power supply to ensure the signal’s bidirectional transmission index.
