1. Product profile
1.1 General description
The BGA3018 MMIC is a wideband amplifier with internal biasing. It is designed
specifically for high linearity CATV line extenders and drop amplifiers over a frequency
range of 5 MHz to 1006 MHz. The LNA is housed in a lead free 3-pin SOT89 package.
1.2 Features and benefits
1.3 Applications
 General wideband amplifiers.
 CATV return amplifier; frequency ranges of 5 MHz to 300 MHz.
 CATV infrastructure network driver in optical nodes (FTTx), distribution amplifiers,
trunk amplifiers and line extenders in the frequency range from 40 MHz to 1006 MHz.
 The product is ideally suited for applications as drop amplifiers in CATV distribution
systems such as FTTH
