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
50
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 consump-
tion, single power supply operation and adjustment free
operation with no external parts required to operate the
part as specified.
