LX5533LQ-TR

Product Overview

LX5533LQ-TR is a Microchip RF amplifier, PA/LNA or automotive radio RF IC from Microchip Technology. In an RF design it is normally used as a RF front-end gain, PA driver or tuner amplifier stage, 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: band depends on LX/GMICP/MMA/ATR base number; Microchip families cover ISM, cellular, automotive radio and microwave modules; gain, output power, noise and linearity are exact-base datasheet values; and RF IC bias or PA supply per package. Because RF amplifier parts are layout- and matching-sensitive, LX5533LQ-TR should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
