China Manufacturers CATV Line Bidirectional Amplifier, Find details about China Amplifier CATV, CATV Line Bidirectional Amplifier from China Manufacturers CATV Line Bidirectional Amplifier
Summary
SA1022/SA1022R Field Bi-directional amplifier, down broadband up to 1GHz, it is the good choice for large NGB network.
Characteristics
1. 1000MHz Broadband
2. GaAs MMIC used on the forward path, Power-Double module amplify module are used as output stage, Output level is stable and nonlinear index is good, import high index amplify module are used on return path, its distortion is little and SNR is high.
3. It is more convenient to debug because of plug-in (or adjustable) duplex filters, plug -in fixed (or adjustable) equalizers, plug-in output splitters and scientific and rational on-line detection ports.
4.The equipment can work steadily outdoor under bad environmental condition because of waterproof aluminium case, high reliability switching power supply and lightning protection system.
