Qorvo's RF2484 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 implements differential amplifiers for the modulation inputs, 90 degrees carrier phase shift network, carrier limiting amplifiers, two matched double-balanced mixers, summing amplifier, and an output RF amplifier which will drive 50 ohm from 800MHz to 2500MHz. It is packaged in a small industry-standard QFN 16-pin plastic package.
