TGM2800F bi-directional amplifier

Overview        TGM2800F bi-directional amplifier can be used in CATV network, digital network and telecom network with high gain, low distortion and excellent flatness.Front end adopts high-quality,low-noise and high-linear GaAs chip amplifier. the output adopts imported special CATV power multiplier amplification module. It can be used as a amplifier or a distribution amplifier in bidirectional CATV system and it can also be used as bridging amplifier in the EOC system. Output port branch or distribution are optional. Features         Input stage adopt special CATV high-quality GaAs integrated amplifier,reducing the noise figure
        Output stage adopt imported special CATV multiplier power amplifier module, greatly improved nonlinear distortion characteritics, RF output level up to 108dBuV
        Bi-directional split frequency 42/54MHz or 65/87MHz optional
        Forward output, reverse input share a common external RF test point, easy for forward and reverse channel debugging
        RF output port level, slope fixed adjustable
        Balanced alternative technology, adopt attenuation plug-in table to do balanced adjustment
        Perfect multi-stage surge suppression circuitry,improved anti-lightning strike and anti-surge shocks,further improved the reliability
        Optimized bi-directional configuration design to ensure an excellent price pertableance ratio Technical Specifications
