TGM2800D Bi-directional Amplifier

1.862MHz,Bi-directional 2.1 or 2 way high level outputs 3.GaAs amplify module 4.up to 112dBuV output level 5.low distort

Features

·         Input stage adopt imported CATV headend amplifer modules, input and output stage adopt imported CATV  exclusive power multiplier amplifier module,greatly improved the nonlinear distortion characteristics, RF output level up to 108dBuV

·         Bi-directional split frequency 42/54MHz or 65/87MHz optional

·         Input stage, inter-stage level and the slope are step adjustable; reverse level port independent variable

·         Balanced alternative technology,  adopt attenuation plug-in form to do balanced adjustment

·         Forward output, reverse input share a common external RF test point, easy for forward and reverse debugging

·         Reserved for network management interface,transponder option has national standard network management interface, comply with SCTE HMS and IEC network management standard

·         RF return port has 3-state reverse noise reduction switch and plug-in attenuator, easy for isolating various intrusive interference

·         RF power level monitoring options optional, easy for remotely  real-time monitoring the output signal level of the bi-directional distribution amplifier

·        High-efficiently switching power,perfect multi-stage surge suppression circuitry,improved anti-lightning strike and anti-surge shocks,further improved the reliability
