The organic electroluminescent device includes: a first electrode of conductive and light transmissive material; a light emitting layer of organic material on the first electrode; a second electrode of conductive material on the layer; first and second terminal parts placed on first and second ends of the layer in a first direction crossing a thickness direction of the layer and coupled to the first and second electrodes, respectively; and an auxiliary electrode which is on the first electrode and beside the layer in a second direction crossing the thickness direction and the first direction and coupled to the first electrode, and has an elongated shape extending in the first direction, and made of material having specific resistance smaller than the first electrode, and includes portions with different thicknesses such that sheet resistance is increased with an increase in distance from the first terminal part in a lengthwise direction thereof.

The MEMS switch comprises a substrate with signal-lines having fixed-contacts, a movable-plate with a movable-contact, a flexible support-member supporting the movable-plate, a static-actuator and a piezoelectric-actuator configured to contact the movable-contact with the fixed-contact. The movable-contact is provided at its longitudinal center with the movable-contact, and its both the longitudinal ends with static-movable-electrode-plate. The support-member is four strips disposed on portions outside of the both width ends of the movable plate. The strip extends along the longitudinal direction of the movable plate, provided with a first end fixed to the movable plate, and provided with a second end fixed to the substrate. The piezoelectric-element is disposed on an upper surface of the strip to be located at a portion outside of the width ends of the movable-plate. The piezoelectric-actuator is configured to develop the stress applied to the coupling-portion which is created between each the strip and the movable-plate.

MEMS switch and method of manufacturing the MEMS switch

A bandpass filter includes a combination of a BAW filter and a patterned planar filter with stubs. The BAW filter is composed of a plurality of piezoelectric resonators to give a specific frequency bandpass, while the planer filter is configured to attenuate frequencies near and outside the bandpass. The resonators are connected in a ladder configuration between a first signal transmission path and a ground. The planar filter includes a strip line formed on a dielectric layer to define a second signal transmission path. The BAW filter and the planar filter are formed on a common substrate with the first and second transmission paths connected to each other. The BAW filter, in combination with the patterned planar filter added with the stub, can improve a deep near-band rejection inherent to the BAW filter, exhibiting an excellent out-of-band rejection over certain adjacent frequency ranges outside of the bandpass, and therefore give a sharp and wide bandpass.
