Millimeter wave filter for surface mount applications |
摘要 |
A millimeter wave filter for surface mount applications includes a dielectric base plate having opposing surfaces. A ground plane layer is formed on a surface of the dielectric base plate. At least one low temperature co-fired ceramic layer is positioned over the ground plane layer and defines an outer filter surface. A plurality of coupled line millimeter wavelength resonators are formed as stripline or microstrip and positioned on the outer filter surface. These resonators can be parallel coupled line filters, including hairpin resonators. Radio frequency terminal contacts are positioned on the surface of the dielectric base plate opposite the at least one low temperature co-fired ceramic layer. Conductive vias extend through the at least one low temperature co-fired ceramic layer, ground plane and dielectric base plate and interconnect the radio frequency terminal contacts and coupled line resonator.
