RF2402
5 UHF QUADRATURE MODULATOR
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
Product Description
The RF2402 is a monolithic integrated universal modula-
tion 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 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 accu-
racy. 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.
