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.
