Energy-Saving (Green) Technology and RF/HFC Technology

摘要

GaN is the optimal new technology in the CATV industry. Compared with Si and GaAs, GaN's wider band gap contributes to higher BVgd (≥ 400 volts), allowing for more reliable and higher voltage operation, and for greater ruggedness against ESD and transient energy RFMD GaN-based CATV amplifiers are more linear than are GaAs-based amplifiers, and they maintain better repeatable distortion performance with reduced current than do GaAs or silicon. In HFC networks with Node + (0) or Node + (1, 2, 3) line extenders, GaN greenfield installs require fewer amplifiers; every two GaAs amplifiers in the network could be replaced with one GaN-based amplifier.
