摘要： A filter for filtering electronic signals that has improved isolation. The filter has a multi-layered dielectric block that has six surfaces. The block has a center portion. An input terminal is located on one side surface and has a portion extending onto the adjacent side surfaces toward the center portion. An output terminal is located on another side surface and has a portion extending onto the adjacent side surfaces toward the center portion. A pair of ground terminals are located on two other side surfaces at the center portion. A partial ground plane is located within the dielectric block. The ground plane extends from the center portion toward but not to the input and output terminal portions. The partial ground plane improves isolation of the filter.

摘要： A single side band mixer is composed of standard digital logic elements and field effect transistors, forming a pair of quadrature generators coupled with a mixer-splitter circuit. This design results in a single side band mixer with a bandwidth from DC to at least 100 MHz when realized with CMOS digital logic circuitry. This design allows the single side band mixer to bring particular improvement to circuits including frequency synthesizers, quadrature demodulators and up-converters.

摘要： There is disclosed a low loss and high frequency lumped capacitor that is ideally constructed from LTCC dielectric material and deposited conductive layers. The capacitive plates are shaped as identical and overlapping serpentine conductive paths positioned on either side of a thin dielectric layer, with opposite ends of the conductive paths used for signal contact points. The net effect of the shape of the capacitive plates and the resulting approximately equal and opposite current flows is to cancel the majority of parasitic inductance at high frequencies, thus reducing insertion loss. Filters built using this construction of capacitor exhibit improved high frequency performance. This type of capacitor also has a simplicity of construction that allows integration into LTCC fabricated circuitry without requiring extra layers or terminals.
