General Description

U3770M is a quadrature modulator realized with MATRA MHS’ advanced 0.8 micron CMOS process.

The IC is especially designed for CT2 application in conjunction with TEMIC’s RF/IF signal processor U2760B and a CT2 baseband controller (i.e., AMD PhoXTM controller Am79C4xx).

Together with TEMIC’s PLL IC U2783B and the GaAs front end U7001BG, a complete CT2 chip set is available.
