The MC13821 is a high gain LNA with extremely low noise figure, designed for cellular, GPS and ISM band applications. An integrated bypass switch is included to preserve input intercept performance. The input and output match are external to allow maximum design flexibility. The MC13821 is fabricated using Freescale's advanced RF BiCMOS process using the SiGe:C option and is packaged in the QFN-12 leadless package.
