TAT8857 基础设施功率倍增器
The TAT8857 is ideal for use as a ‘green doubler’ in typical 75 Ohm line amplifier systems where it reduces power consumption 20% compared to existing MMIC solutions in standard 24 volt operation. The TAT8857 is also versatile, designed for distribution node applications from 40-1002 MHz; it can also be operated on 12 volts for optimal efficiency. The TAT8857 utilizes on-chip linearized, integrated pHEMT and MESFET technology to provide low distortion and configurable gain from 22-27 dB. The TAT8857 is ideally suited for manufacturers building CATV infrastructure solutions including line amplifiers and in distribution nodes where low current consumption and high performance is especially desirable. The device offers better optimized Third Order Distortion performance compared to legacy solutions and comes in a standard SOIC-16 package. TAT8857 samples and evaluation boards are now available.
