Introduction
HHA-MB870-40A is two way Trunk Amplifier with two way (or three way ) output.It is adaptable to Coaxial Trunk line of the HFC system signal amplification.Our product offers high gain, high output levels, with good performance of CTB\CSO and 16 dB return loss .The frequency of four diplex Filter options, and offers AGC/MGC function. Factory set-up is two output port, a third output is user-configurable via splitter or directional coupler plug-in.

Characteristics
 .Use Enhanced Gallium Arenide (E-GaAs) modules in Forward Path;
.High Gain;
.High output levels;
.Adjusting the plug of the frequency respond, can effectively compensates the raised package which produced by weaken of the electric cable non-linearity;
.Outdoor casting aluminum housing adopts international advanced passivating treatment and the double-decked waterproof craft. The unit is not only anti-corrosive and anti-aging, but also has a good radiation, and has a good waterproof performance and an anti-electromagnetic performance;
.Adjustable input level and output level in forward path and return path, convenient for system adjustment;
.Use the high quality bi-directional plug connection, convenient for network update;
.The highly effective low noise switching power supply, guarantees the signal two-way transmission target
