A drop-in circulator, dubbed the 3G7BH, spans 5.2 to 11 GHz. It exhibits insertion loss below 0.95 dB over the entire band while handling 20 W of incident RF power from -20 to +85C. The 3G7BH, which exhibits isolation and return loss of 13 dB, promises to match well to RF circuitry on which it is placed. It is housed in a 0.75-in.-square, stainless-steel housing.
