SILICON-BASED SURFACE-MOUNT I-Q MODULATORS/DEMODULATORS FOR RFID AND WIRELESS APPLICATIONS

摘要

Two new surface-mount I-Q modulators/demodulators have been added to the "RFID by M/A-COM" series of products that are designed for RFID, wireless handset and base station applications. The MA4IQP900L-1291T and the MA4IQP900H-1291T HMIC I-Q modulators/demodulators are compact and highly functional devices using low and high barrier silicon Schottky diodes, respectively, and compliment the existing MA4IQP900M-1291T medium barrier silicon device. The two new modulators cover the same 850 to 960 MHz operating frequency range in a compact 6 mm square MLP surface-mount package.
