MMG3H21NT1
Broadband High Linearity Amplifier
The MMG3H21NT1 is a General Purpose Amplifier that is internally
input matched and internally output matched. It is designed for a broad
range of Class A, small-signal, high linearity, general purpose applica-
tions. It is suitable for applications with frequencies from 0 to 6000 MHz
such as Cellular, PCS, BWA, WLL, PHS, CATV, VHF, UHF, UMTS and
general small-signal RF.
