Overview

This application note (AN11296) details the schematic and layout requirements for using the NXP BGA3018 as a wideband amplifier between 40 MHz and 2600 MHz. The BGA3018 is a BiCMOS MMIC designed for CATV applications, packaged in a 3-pin SOT89. The document provides a complete evaluation board design, including a bill of materials featuring Murata and Yageo components, PCB layout strategies for optimal ground inductance, and 75 Ω input/output matching. It includes extensive measurement data at 5V and 8V supply voltages, covering gain, return loss, noise figure, output P1dB, IP2, IP3, and distortion metrics like CTB and CSO.
