RF2402

RF2402 5 Typical Applications Digital and Spread-Spectrum Systems GMSK, QPSK, DQPSK, QAM Modulation GSM and D-AMPS Cellular Systems AM, SSB, DSB Modulation Image-Reject Upconverters UHF QUADRATURE MODULATOR Product Description The RF2402 is a monolithic integrated universal modulation system capable of generating modulated AM, PM, or compound carriers in the UHF frequency range. The IC contains all of the required components to implement the modulation function including differential amplifiers for the baseband inputs, a 90° hybrid phase splitter, limiting LO amplifiers, two balanced mixers, a combining amplifier, and an output RF amplifier which will drive a 50 Ω load. Component matching, which can only be accomplished with monolithic construction, is used to full advantage to obtain excellent amplitude balance and high phase accuracy. The unit features low power consumption, single power supply operation, and adjustment free operation with no external parts required to operate the part as specified.
