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
