Line extender Rayvert 870 MHZ con retorno
The LEX80 is an advanced bi-directional amplifier typically deployed in the line portion of the RF network, providing RF signal gain with minimal distortions. It has an amplifier module with a power supply range 40-90Vac at 50/60Hz. Configurable as a single output device, LEX80 offers high gain, compatible plug-in accessories, two diplex filters, and an optional second output via a modular splitter or directional coupler.
LEX80 amplifiers incorporate high quality push-pull and parallel GaAs hybrids to provide the highest output and lowest distortion levels possible. A regulated power supply along with a die casting aluminum alloy heat sink case provides the reliability required for operation in the most hostile environments. LEX80 has two test points, one for forward input and one for forward output, directly accessible from the housing cover, which simplifies the maintenance. It also has the optional accessories CTF and Therm for compensating the loss of cable caused by the change of temperature in both forward and return path.
