1 Introduction
The MC13820 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 MC13820 is fabricated using Motorola's
advanced RF BiCMOS process using the SiGe:C option
and is packaged in the QFN12 leadless package.
