Product Overview
Description
Description
Adopt SOT-115 encapsulate CATV dedication RF module in forward path and low-noise micro push-pull circuit in return path.
Have good index, small consumption, high reliability and performance to price ratio, suitable for medium and small CATV bi-directional network.
Features
(1) Adopt low-noise micro tube circuit or SOT-115 encapsulate CATV dedication RF module in forward path, steady output level, good Non-linear; adopt low-noise micro tube push-pull circuit in reverse path, small distortion and high signal to noise ratio.
(2) Plug-in dual-filter and fixed (or VAR ) equalizer and attenuator, plug-in output tap, science detector is rational, testing conveniently.
(3) Waterproof cast-aluminum shell, high-reliable power switching, tight anti-thunder system, have guaranteed that the equipment can work steadily in succession for a long time in the abominable environment of field.

Special Notice
The performance parameters of this manual according to GY/T185-2002: Network Entry Technical Requirements and Measurements Method of CATV Amplifier.
At the range of 750MHz (112.25~743.25MHz) when testing the C/CTB and C/CSO, set 79 PAL-D imitate TV channels signal; set 93PAL-D imitate TV channels signal at the range of 862MHz (112.25~855.25MHz). Choose f1=65MHz, f2=63MHz and f3=57MHz to test when measuring index of max output level in upgo transmission. The index of "Carrier to Second Order Inter-modulation Ratio" is tested under the condition of 110dBuV output level, and choose f1=10MHz, f2=60MHz and f3=50MHz three point to test.
