RFCI Drop-in Flange Mount Circulators utilize the latest technology in miniaturization to assure a fit into the most compact assemblies.
RFCI has developed a series of Drop-in Flange Mount Circulators for applications in high performance linear power amplifiers. These devices are specifically designed to be mounted with standard hardware within your chassis. Their connection Tabs are suitable for soldering to the mating circuit boards.
Applications:
Communication systems
Narrow S, C, X and Ku-Bands Radar
