Radar
ADI's comprehensive portfolio and custom development provide complete RF-to-bits solutions for a wide range of commercial and defense radar systems. The high resolution of ADI’s ADC/DAC products and the precision of ADI’s clock and synthesizer modules, mixers and filters provide the high signal-to-noise ratio required for detection accuracy and AESA element balance. ADI’s next-generation CMOS and SiGe solutions and advanced sub-systems support increased integration, enabling new system concepts and multi-function systems to be realized.
Analog Devices recognizes the need for high power, high-efficiency amplifiers to support long ranges, reduce the number of amplification stages, and thereby reduce the size of transmit/receive modules. Advancements in semiconductor fabrication processes, such as Gallium Nitride (GaN), have enabled ADI amplifier/combiner designs to replace traditional Traveling Wave Tube (TWT) amplifiers, reducing footprint and cooling requirements while increasing reliability.
