Overview

RF2424 5 Typical Applications • Digital Communications Systems • GMSK,QPSK,DQPSK,QAM Modulation • GSM and D-AMPS Systems • Image-Reject Upconverters • Spread Spectrum Communication Systems • AM, SSB, DSB Modulation UHF QUADRATURE MODULATOR Product Description The RF2424 is a monolithic integrated quadrature modulator IC capable of universal direct modulation for highfrequency AM, PM, or compound carriers.
Maximum output power is +7.
5dBm, which is achieved with low input I and Q signal levels.
This low-cost IC implements differential amplifiers for the modulation inputs, 90° carrier phase shift network, carrier limiting amplifiers, two matched double-balanced mixers, summing amplifier, and an output RF amplifier which will drive 50 Ω from 700MHz to 1000MHz.
