RF2464
5 VHF QUADRATURE MODULATOR
Typical Applications
• Digital and Spread-Spectrum Systems
• AM, SSB, DSB Modulation
• GMSK, QPSK, DQPSK, QAM Modulation • Image-Reject Upconverters
• Private Mobile Radio and TETRA systems
Product Description
The RF2464 is a monolithic integrated universal modula-
tion system capable of generating modulated AM, PM, or
compound carriers in the VHF and UHF frequency range.
The IC contains all of the required components to imple-
ment the modulation function including differential amplifi-
ers 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
50Ω 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 coDnastuamSph-eet4U.com
tion, single power supply operation and adjustment free
operation with no external parts required to operate the
part as specified.
