SPECIFICATION
Quick Detail:
●PHILIPS or MOTOROL a low noise push pull amplifier modules are used as forestage of forward path. PHILIPS or NEC Power-Double gallium arsenide modules are used as output stage. Output level is high and nonlinear index is good.
●PHILIPS or MOTOROLA return amplifier modules are used as backward path. It's distortion is little and SNR is high.
●It is more convenient to debug, because of plug-in duplex filters, plug-in fixed (or continuously adjustable) equalizers, plug-in output splitters and scientific and rational on-line detection ports.
●Optimal high performance Automatic Gain Control(AGC) circuit in SA812 cause precise control and steady link signal.
●Optimal high performance Automatic Temperature Compensation(ATC) circuit in SA812 cause precise control and steady link signal.
●The equipment can work steadily outdoor under bad environmental condition, because of waterproof aluminum case, high reliability switching power supply and lightning protection system.
