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° carrier phase shift network, carrier limiting amplifiers,

two matched double-balanced mixers, summing amplifier, and an output

RF amplifier which will drive 50 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.
