RF2480PCBA(Rev_A4-1) Datasheet PDF - RF Micro Devices

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 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 50 from 800MHz to 2500MHz. Component matching is used to obtain excellent amplitude balance and phase accuracy.
