Introduction

F1431B is a high-linearity RF digital variable gain amplifier designed as a power amplifier driver in transmitter applications. The device provides 14dB gain, +41.1dBm OIP3, and a noise figure of 4.2dB at 2.0GHz. Its digital step attenuator features a 23dB range with 0.5dB steps, operating over a frequency range of 0.35GHz to 3GHz, with a single tuning circuit. The device operates from a single 5V supply at 150mA current consumption. The F1431B is housed in a 4×4 mm, 24-pin thin QFN package. Its RF input and RF output impedance of 50Ω facilitates integration into RF signal paths.
