Product Description
The RF2422 is a monolithic integrated quadrature modulator IC capable
of universal direct modulation for high-frequency AM, PM, or compound
carriers. This low-cost IC implements differential amplifiers for the modu-
lation inputs, 90擄 carrier phase shift network, carrier limiting amplifiers,
two matched double-balanced mixers, summing amplifier, and an output
RF amplifier which will drive 50惟 from 800MHz to 2500MHz. Component
matching, which can only be accomplished with monolithic construction,
is used to full advantage to obtain excellent amplitude balance and phase
accuracy.
