The RF2484 is a monolithic integrated quadrature modulator IC capable
of universal direct modulation for high-frequency AM, PM, or compound
carriers. This low-cost IC features excellent linearity, noise floor, and
over-temperature carrier suppression performance. The device imple-
ments 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 800MHz to 2500MHz. It is packaged in a small industry-stan-
dard QFN 16-pin plastic package.
