1. Summary
SA801H Indoor Bi-directional Amplifier are special amplifiers designed for the last "1km" of the bi-directional transmission network. Special CATV RF modules are used as forward channel; Microwave tube push-pull circuit with low noise are used as backward channel; It has the characteristics of low power consumption,high reliability and excellent cost performance. And it is suitable for small and medium sized CATV bi-directional transmission network.
2. Performance Characteristics
Microwave tube push-pull circuit with low noise or special CATV RF modules packaged in SOT-115 are used as forward channel whose output level is stable and nonlinear indicators are good; Microwave tube push-pull circuit are used as backward channel whose distortion is low and signal-to-noise ratio is high.
It is more convenient for debug engineering debug, because of the plug-in diplexer filters with built-in adjustable equalizers, adjustable attenuator, plug-in output splitter and scientific and reasonable ports for online test.
These equipment will work in the field rugged environment for a long time continuously, because of the aluminum alloy casing, good heat dispersing performances, beautiful looks, dependable linear power supply and lightning protection systems.
