Designed and developed specifically for TETRA radio applications, is a coaxial ferrite circulator / isolator sourced by Aaren Technology, and exclusively available in the UK from Admiral Microwaves Ltd. The AT11B-AP200-AF-AM is part of a wider range ferrite circulators and isolators suitable for a variety of RF & microwave applications in both the commercial and defence communications sectors.

This particular circulator operates across the frequency range of 380 to 410MHz making it ideal for use with TETRA transmitters and other base station components such as distributed antenna systems. This specific TETRA unit has an average power forward rating at 100W. Insertion loss is specified at 0.40dB at room temperature and 0.45dB across the extended
-40 oC to 85oC temperature range, with a corresponding VSWR figure of 1.17:1 and an Isolation figure of 22dB

Isolators are additionally available with a range of terminating loads up to 100W. Connector options include SMA and N-type in male and female configurations.

The Aaren range of ferrite circulators and isolators cover frequency ranges from 200MHz right up to 40GHz in drop-in, coaxial or waveguide designs. All products are very cost competitive and are not subject to ITAR or other export control legislation.

Components are RoHS compliant, in production now, and samples are available from Aspen Electronics.
