- •
Molded Interconnect Device technology was used to realize a self-biased circulator.
- •
This is the first demonstration of a non-reciprocal effect in MID technology.
- •
Pre-oriented hexaferrites enable a self-biased circulation.
- •
(La,Co)0.3-SrM hexaferrite cylinder shows a remanence to saturation ratio of 90%.
- •
The measured self-biased circulator shows insertion losses of 3.3 dB and an isolation level of 13.9 dB at 30.7 GHz.
