MMH3111NT1
Broadband High Linearity Amplifier
The MMH3111NT1 is a general purpose amplifier that is internally
input and output prematched. It is designed for a broad range of Class A,
small--signal, high linearity, general purpose applications. It is suitable
for applications with frequencies from 250 to 4000 MHz such as cellular,
PCS, WLL, PHS, CATV, VHF, UHF, UMTS and general small--signal RF.
