Functional Block Diagram

Product Description

The RF2480 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

50 from 800MHz to 2500MHz. Component matching is used to obtain

excellent amplitude balance and phase accuracy.
