LE - 1218A 1.2GHz Amplifier

Query


LE-1218A RF Amplifier is a 1.2 GHz bandwidth two-way amplifier. It provides excellent forward and reverse path performance combined with high reliability and a user-friendly layout. GaAs technology is used, that guarantees the excellent CTB and CSO performance. Both output level and slope can be configured electronically. There are 3 bit digital tube display and adjust keypad, for rapid initial setup or for adjustments that are needed as network requirements shift.

The number of amplifier plug-ins is reduced to a minimum to help operators keep inventory and costs down. The full-range electronic attenuators and equalizers offer improved function and make it possible to achieve the same adjustment range as with plug-in solutions.

The frequency split can be changed in the field for system upgrading easily by plug-in diplex filters, HPF and LPF.

 

Features

l  Supports 1.2 GHz bandwidth

l  Up to 204 MHz with return bandwidth

l  Electronically adjust for attenuation and equalization, reduce plug-in accessories

l  On site changing frequency split 

l  Switch the reverse path gain adjust and turn-off

l  Compact design, small and exquisite

l  GaAs technology in use

l  Improved ESD and Surge protection

l  Low noise figure

l  Second output can be selected via splitter, directional coupler or tap
