The FCI Series from Ducommun are Iso-Adapters that operate from 8.2 to 70 GHz. Iso-adapters provide a transition from a waveguide interface to a coaxial interface with high reverse isolation. They have an insertion loss of less than 1 dB and provide an isolation of over 18 dB. The iso-adapters provide circulation functions between a waveguide and coaxial interface and cover common radar and wireless communication frequency bands. They can be configured with a standard waveguide interface and N-type, SMA, K, 2.4 mm or V coaxial connectors. The FCI Series iso-adapters have very compact sizes that can be easily inserted into the sub-assembly with a minimum size increase. They are suitable for application such as module integration, port isolation and transceiver sub-systems.
