Rev. 3 — 26 September 2013
Product data sheet
1. Product profile
1.1 General description
The BGA3012 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
Internally biased
Flat gain
Noise figure of 3.1 dB
75 input and output impedance
High linearity with an IP3O of 40 dBm and Operating from 5 V to 8 V supply
an IP2O of 60 dBm
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

[1] The fundamental frequencies (f1) and (f2) lay between 40 MHz and 1006 MHz. The intermodulation product (IM3) is 2 f2 f1, where
f2 = f1 6 MHz. Input power Pi = 20 dBm.
[2] The fundamental frequencies (f1) and (f2) lay between 40 MHz and 1006 MHz. The intermodulation product (IM2) is f2 f1, with
40 MHz < f1-f2 < 1006 MHz. Input power Pi = 20 dBm.
