LA-1218T 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 adjusted using standard JXP PADs to minimize the spares.
The frequency split can be changed in the field for system upgrading easily.
