Introduction
The MC13770 is a single band front-end IC designed for
wireless receiver applications. It contains a low noise
LNA and a high linearity mixer. The LNA is integrated
with a bypass switch to preserve input intercept
performance. The device is fabricated using Freescale's
Advanced RF BiCMOS process using the SiGe:C option
and is packaged in a 12 pin Quad Flat Non-leaded
package.

Note: Maximum Ratings and ESD
1. Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be
restricted to the limits in the Electrical Characteristics tables or Pin Descriptions section.
2. ESD (electrostatic discharge) immunity meets Human Body Model (HBM)
100 V and Machine Model (MM) 30 V.
Additional ESD data available upon request.
