BGA3031J

Product Overview

BGA3031J is a RF MMIC amplifier / LNA / gain-block IC from NXP Semiconductors. In an RF design it is normally used as a front-end gain or IF/RF gain stage in a 50 Ω signal path, so the useful sourcing checks are not only the ordering code but also the operating band, gain behavior, output level, package footprint and bias conditions.

For this model, the key application data to verify are: NXP BGA/BGU family covers RF receiver/front-end bands; exact frequency and gain are base-number specific; check the NXP datasheet for gain, noise figure, IP3 and matching network for this exact base; and low-voltage RF IC bias, typically single-supply. Because RF amplifier parts are layout- and matching-sensitive, BGA3031J should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.

Key Features
