Atmel U3770M
The U3770M is a quadrature modulator realized using Atmel Wireless & Microcontrollers’ advanced 0.8 micron CMOS process. The IC is especially designed for CT2 applications in conjunction with Atmel Wireless & Microcontrollers’ RF/IF signal processor U2760B and a CT2 baseband controller (i.e., AMD PhoXTM controller Am79C4xx). A3, 07-Sep-00 1 (6) U3770M Functional Description The U3770M has been designed to reduce power consumption and cost of CT2 devices.- Max Operating Temp : 70°C
- Min Operating Temp : -5°C
