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
