Broadband High Linearity Amplifier
The MMH3111NT1 is a general purpose amplifier t hat is internally
input and output prematched. It is des igned for a broad range of Class A ,
small -- s ignal, high linearity, general purpose applications. It is s uitable
for applications with frequencies from 250 to 4000 MHz such as cellular,
PCS, WLL, PH S, C ATV, VH F, UH F, UMT S and general s mall--signal RF.
