●One microwave low noise amplification circuits is added in each forward path forestage of SA822 high-performance power doublers amplifier modules are used as output ports. Its output level is high and Nonlinear Index is good.

●Import PHILIPS or MOTOROLA low noise push-pull amplification modules are used as forward path of SA822 amplifiers. Its 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.

●The equipment can work steadily outdoor under bad environmental condition, because of waterproof aluminum case, high reliability switching power supply and lightning protection system.
