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
l Input stage adopt special CATV high-quality GaAs integrated amplifier, reducing the noise figure
l Output stage adopt imported special CATV multiplier power amplifier module, greatly improved nonlinear distortion characteritics, RF output level up to 108dBuV
l Bi-directional split frequency 42/54MHz or 65/87MHz optional
l Forward output, reverse input share a common external RF test point, easy for forward and reverse channel debugging
l RF output port level, slope fixed adjustable
l Balanced alternative technology, adopt attenuation plug-in table to do balanced adjustment
l Perfect multi-stage surge suppression circuitry,improved anti-lightning strike and anti-surge shocks,further improved the reliability
l Optimized bi-directional configuration design to ensure an excellent price pertableance ratio
