SA1100 outdoor 2 output trunk amplifier is mainly used for bidirectional trunk transmission of CATV television image signal, digital TV signal, telephone voice signals and data (or compressed data) signal. Advanced and mature circuits, scientific and reasonable process structures and high quality materials, ensure the excellent performance.
Features
■1003MHz bandwidth design.
■Forward path: The pre-stage adopts GaAs MMIC, output stage adopts the newest imported high index power doubly module, achieve high output level, low distortion and high SNR.
■This outdoor 2 output trunk amplifier is more convenient to debug because of the plug-in duplex filter, equalizer, attenuator, output tap and the scientific and reasonable on-line detection ports.
