CATV trunk amplifier
Technical characteristics of trunk amplifier:
The front and rear two-stage equalization adjustment circuit makes the signal level flat, effectively solves the level “bulge” phenomenon, and enables the level to be output with a slope, which is suitable for long-distance cable TV transmission.
The unique integrated circuit temperature compensation can improve the influence of the high and low-temperature difference on the cable and amplifier, and automatically control the output level.
The branch type and distribution type output selection function is suitable for the actual circuit needs and saves expenses; the output feed display function is convenient and practical.
Using double-sided metal holed circuit board, and a high-quality toroidal transformer power supply, the amplifier has excellent high-frequency performance and stable and reliable operation.
CATV special aluminum alloy die-casting and the plastic-spraying shell has good rainproof, heat dissipation, and shielding characteristics.
220V AC power supply or 60V centralized feed type is optional.
