Profile: RF Micro Devices, Inc. designs and manufactures semiconductor components. Our product line includes amplifiers, couplers, attenuators, demodulators, circulators, isolators, modulators, and mixers. Our CPA-0501-510H coupler is designed for applications that require small low cost and highly reliable surface mount components. Applications may be found in broadband wireless and other communication systems. These units are built Lead-Free and RoHS compliant. Our CGA-0116 is a high performance 50-870 MHz 3-output broadband CATV active splitter/amplifier, designed for operation at 5 volts. It offers flat gain, high isolation, high IP2, and low power consumption. Our 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 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 800 MHz to 2500 MHz. Component matching, which can only be accomplished with monolithic construction, is used to full advantage to obtain excellent amplitude balance and phase accuracy.
