With the industry’s widest portfolio of PLL products, we can cover virtually all your PLL needs.

Radio frequency analog-to-digital converters (RF ADCs) are special types of ADCs designed to convert RF signals, which are typically high frequency analog signals, into a digital format. This is crucial in various applications like radar, electronic warfare, satellite communications, instrumentation and measurement, industrial automation and robotics, digital healthcare, data centers, and optical receivers, where capturing and processing RF signals is essential. Analog Devices offers a broad portfolio of RF ADCs with the industry's best performance, power, and size to offer SWaP-C efficient solutions to our customers.

Radio frequency digital-to-analog converters (RF DACs) are high speed DACs designed to convert digital signals into analog signals directly at radio frequencies, without the need for an intermediate analog modulation stage. This direct conversion offers several advantages, including higher performance, reduced complexity, and increased efficiency, especially in applications like software-defined radios (SDRs) and multiband transmitters, suitable for aerospace and defense, instrumentation and measurement, industrial automation and robotics, digital healthcare, data centers, satellite communications, commercial aviation, and space markets. Analog Devices offers a broad portfolio of RF DACs with the industry's best performance, power, and size to offer SWaP-C efficient solutions to our customers.
