Quick Detail:

●The microwave low noise amplification circuits are used as forward and backward paths of SA831 products. CATV special RF modules encapsulated by SOT-115 are used as forward paths of SA831 products. The microwave low noise amplification circuits are used as backward paths of SA831 products.
●It is more convenient to debug, because of plug-in duplex filters, plug-in fixed (or adjustable) equalizers, plug-in fixed (or adjustable) attenuator 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.
