U3770M Datasheet (ATMEL Corporation) - CT2 I/Q Modulator and Clock Circuitry

U3770M, CT2 I/Q Modulator and Clock Circuitry

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 Ph
