Product Description

1. Summary
WA8200RP-1G is the preamplifier which specifically designed for the large and medium-sized head-end machine room. Adopt CATV dedicated electronically controlled RF attenuation chip with ultra-low distortion, excellent linearity to constitute the attenuation and equalization circuit, replaced the traditional manual adjustment. Microprocessor controls parameters, LCD displays working status. High adjustment accuracy, more convenient and intuitive operation. The output adopts NEC GaAs power doubler module to ensure excellent system performance index. It's the best choice for the transform of large and medium-sized head-end machine room.
