Abstract
A reconfigurable bandpass filter including at least a tunable planar combline filter including varactor diodes arranged on a carrier board. For automatic calibration of adjustment of blocking voltage during operation, the reconfigurable bandpass filter includes a filter control offering an external abstracted interface. A memory is connected with the filter control. The memory stores calibration data. For approximating of the best possible filter characteristic, the filter control determines, based on memorized data, the best configuration of tuning voltages. The reconfigurable bandpass filter can be used in the field of secondary radar systems.
