LA - 1208T 1.2GHz Amplifier

Query


LA-1208T RF Amplifier is a 1.2 GHz bandwidth two-way amplifier. It features two gain modes (High gain or Low gain) for more flexible operation. Different gain mode can be set in the field depending on the system status. Forward higher gain can be used in distribution systems and lower gain is suitable for line extension application. Return gain can also be set to high or low mode depending on the link loss in the return path.

GaAs technology is used, that guarantees the excellent CTB and CSO performance. Both output level and slope can be adjusted using standard JXP PADs to minimize the spares.

The frequency split can be changed in the field for system upgrading easily.
