Product Description The RF2424 is a monolithic integrated quadrature modulator IC capable of universal direct modulation for high frequency 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 50Ω from 700MHz to 1000MHz. Features • Single 2.7V to 5.5V Power Supply • +7.5dBm Output Power • No Tuning Required • Low LO Input Level • Digitally Controlled Power Down Mode • 700MHz to 1000MHz Operation Typical Applications • Digital Communications Systems • Spread Spectrum Communication Systems • GMSK,QPSK,DQPSK,QAM Modulation • GSM and D-AMPS Systems • AM, SSB, DSB Modulation • Image-Reject Upconverters
