Rev. 2 — 25 February 2015
Product data sheet
1. Product profile
1.1 General description
The BGA3021 MMIC is a dual wideband amplifier with internal biasing. It is a Medium
Power Amplifier (MPA), specifically designed as an output stage for high linearity CATV
optical mini- and midi-nodes, operating over a frequency range of 40 MHz to 1200 MHz.
The MPA is housed in a lead free 8-pin HSO8 package.
1.2 Features and benefits

 Fundamental frequency f1 = 500 MHz, fundamental frequency f2 = 501 MHz. The intermodulation product (IM3) is measured at
2 f1 f2 = 499 MHz. The output power of the fundamental frequencies is 10 dBm per frequency.
 Fundamental frequency f1 = 240 MHz, fundamental frequency f2 = 260 MHz. The intermodulation product (IM2) is measured at
f1 + f2 = 500 MHz. The output power of the fundamental frequencies is 10 dBm per frequency.
