High-q tank
Patentansökan, 2001

LC tank formed on a 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. According to one embodiment of the invention a pair of back to back coupled diodes (18, 19) are arranged between the input terminals of the tank and a pair of DC leads (16, 17) are arranged between the midpoint of the inductor structure and the midpoint between the diodes. The tank according to the invention can be implemented in MMIC devices using standard semiconductor substrates without any special treatment of the substrate being needed
