Product Description

The RF2484 is a monolithic integrated quadrature modulator IC capable of universal direct modulation for highfrequency AM, PM, or compound carriers. This low-cost IC features excellent linearity, noise floor, and over-temperature 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, summing amplifier, and an output RF amplifier which will drive 50Ω from 800MHz to 2500MHz. It is packaged in a small industry-standard LCC 16-pin plastic package.
