ABSTRACT:
A miniature wideband bias tee that has a small package size. The bias tee has a low temperature co-fired ceramic substrate with a top surface and a bottom surface. A first inductor is located within the substrate. A second inductor is attached to the top surface and has a core with a wire wound on the core. Terminals are located on the top and bottom surfaces. Ends of the wire are connected to terminals on the top surface. A capacitor is mounted to terminals on the top surface. Several vias extend through the substrate and electrically connect the terminals to the inductor and capacitor.
