Stripline broadband filter high band microwave

摘要

The proposed invention relates to the field of microwave technology and can be used in frequency selective circuits paths broadband radio systems, telecommunications, radar and measurement systems. Target Utility Model - reduction of insertion loss, level of VSWR reduction in the operating frequency range, size reduction, simplification of the device structure. The strip broadband filter upper microwave frequency band formed on the dielectric substrate, on the lower base of which is applied the display conductor and comprising three series-connected capacitive element, realized in the form of a thin film capacitor, and two parallel-connected inductive elements, the dielectric substrate is a three-layer, wherein the upper layer disposed input and output microstrip feed lines, a series connection of capacitive elements in the form of thin film to ndensatorov, parallel-connected inductive elements implemented in the form of a rectangular stack of spirals arranged at the upper and the second inner layer and a conductor connected to the screen on the lower base substrate through the metallized vias. The material of the substrate selected low temperature ceramic as a dielectric thin film used for the realization of the capacitive elements selected film monoaluminate neodymium.
