The RF2480 is a monolithic integrated quadrature modu-
lator 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-tem-
perature carrier suppression performance. The device
implements differential amplifiers for the modulation
inputs, 90° carrier phase shift network, carrier limiting
amplifiers, two matched double-balanced mixers, sum-
ming amplifier, and an output RF amplifier which will drive
50
from 800MHz to 2500MHz. Component matching is
used to obtain excellent amplitude balance and phase
accuracy.
