Abstract: An RF diplexer circuit device using modified lattice, lattice, and ladder circuit topologies. The diplexer can include a pair of filter circuits, each with a plurality of series resonator devices and shunt resonator devices. In the ladder topology, the series resonator devices are connected in series while shunt resonator devices are coupled in parallel to the nodes between the resonator devices. In the lattice topology, a top and a bottom serial configurations each includes a plurality of series resonator devices, and a pair of shunt resonators is cross-coupled between each pair of a top serial configuration resonator and a bottom serial configuration resonator. The modified lattice topology adds baluns or inductor devices between top and bottom nodes of the top and bottom serial configurations of the lattice configuration. A multiplexing device or inductor device can be configured to select between the signals coming through the first and second filter circuits.

Abstract: Methods of fabricating semiconductor devices and Radio Frequency (RF) components are provided. The method includes providing a circuit layout on a semiconductor layer and providing one or more sacrificial connections to connect bump pads in the circuit layout. The method also includes testing the circuit layout using the one or more sacrificial connections and removing at least a portion of the one or more sacrificial connections. In this way, the performance of the semiconductor device is improved by reducing or avoiding capacitive or inductive leakage paths that can be caused by leftover materials.

Abstract: The invention relates to a micro-acoustic filter having a first and a second converter, in which the electromagnetic and capacitive cross-talk between the first and second converters is compensated for by providing additional coupling capacitors and additional current loops. Additional coupling capacitors and current loops are arranged in such a manner that they can counteract the sign of the natural coupling specified by the design and thus completely compensate for said coupling.
