ABSTRACT:
A variety of embodiments of varactor diodes are disclosed ranging from an N.times.N matrix assembly of individually packaged diodes arranged in N rows and columns to a multi-continuous layered varactor. The matrix assembly varactor has N rows of discrete devices electrically coupled in parallel and multiple rows vertically aligned and electrically coupled in series to each other. The overall matrix assembly capacitance equals the individual diode capacitance of such assembly. When used as a tuning component across a tank coil transmission line, the RF voltage across any device in the matrix assembly is equal to the tank voltage divided by N.
