AMC7891: We want to know that what application does AMC7891 and LMP92018 mainly used for?

Hi Elsa,

The AMC7891 and LMP92018 are primarily used for RF power amplifier gate biasing applications.  These are found in any RF system that uses LDMOS, GaAs, or GaN power amplifiers.  We sometimes label this as "analog monitoring and control".

Thanks,

Paul
