Product Description
1. Summary:
Specially used in CATV bi-directional transmission network final "1km" home amplifier.
Adopt low-noise micro tube push-pull circuit in forward return path of HT8028-00 and HT7028-00. Adopt SOT-115 encapsulate CATV dedication RF module in forward path and low-noise micro push-pull circuit in return path.
Have good index, low consumption, high reliability and performance to price ratio, suitable for medium and small CATV bi-directional network.
2. Performance Characteristic:
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.
Plug-in dual-filter and fixed (or VAR ) equalizer and attenuator, plug-in output tap, science detector is rational, testing conveniently.
Waterproof cast-aluminium 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.
