Abstract
A balanced inductor formed on lossy substrate material having adjacent strips leading current in opposite directions and being arranged in such a way that substrate currents relating to individual strips (1) induced in the lossy substrate (3) are balancing out one another leading to high Q-values. The inductor structure according to the invention can be implemented in MMIC devices using standard semiconductor substrates and do not require any special treatment of the substrate being needed.
