Description

GME's 1.2G amplifier is a low-cost, high-reliability, Compact In size amplifier. It have a width bandwidth and high level / high slope output capability that delivers reliable performance supporting DOCSIS 3.1 frequencies to 1.22GHz. The unique design offers configurations for 42 or 85 or 204MHz upstream bandwidth requirements.

The amplifier applications for indoor advanced HFC network installations in apartment buildings, hotels, schools, hospitals ..., having high RF amplification requirements. Designed with high gain this amplifier can be mounted directly to a wall with increased heat dissipation properties and low power consumption.

This CATV Amplifier For Building uses the latest 1.22GHz GaAs Push Pull technology versions providing superior distortion performance and low noise figure.

Technician friendly controls feature variable attenuators and equalizers facilitating greater flexibility when adjusting the amplifier. The internal power supply accepts input voltages from 100-240V at frequencies of 50 or 60Hz without adjustment.

38dB forward gain, 27dB reverse gain.
Enables high forward bandwidth up to 1220 MHz
42/54, 85/102, 204/256MHz available diplex filter options.
Aluminum Chassis Provides Excellent Heat Dissipation.
Variable attenuators and equalizers.
-20dB external inpuVoutput test points.
Surge protected up to 6kV/3kA on IN/OUT ports.
100-240VAC internal switching power.
