The A-Series utilizes precision thin-film technology on a ceramic substrate to maintain signal integrity across temperature and environmental extremes. Measuring just 0.080 by 0.065 inches, the components are engineered to fit into space-constrained assemblies such as phased-array antennas, radar systems, and satellite communication hardware. By offering pin compatibility with existing industry-standard chip attenuators, Knowles intends to simplify the upgrade path for engineers seeking to boost power handling without requiring extensive PCB redesigns.
Knowles Targets RF Market Expansion with New A-Series Attenuators
Knowles Corporation is pushing deeper into the radio frequency component market with the launch of its ATT A-Series attenuators. Designed for high-frequency environments ranging from DC to 20 GHz, the new surface-mount devices aim to provide a compact, rugged alternative for dense electronics in defense and aerospace applications.
Robert Wagner, Vice President of RF and Microwave Products at Knowles, noted that the line addresses a specific gap in the market by combining broadband performance with an MSL 1 rating and high ESD robustness. The units support power handling up to 6.5 W CW at 100°C and operate within a range of -55°C to +125°C. Beyond standard attenuation values from 0 dB to 20 dB, the company is offering custom configurations to meet specialized design requirements, signaling a move to position itself as a comprehensive source for integrated RF signal chain components.
