Spurious Mode Suppression in Coupled Resonator Filters
IEEE MTT-S International Microwave Symposium Digest, 2005., 2005The Coupled Resonator Filter (CRF) is a new type of Bulk-Acoustic-Wave (BAW) device in which two piezoresonators are stacked on top of each other in a way that a certain degree of acoustic interaction occurs. For a proper frequency response, a method for suppression of spurious resonances is of utmost importance.

Suppressing ripple distortions and spurious pistons in phase-shifting interferometry
Journal of the Optical Society of America A, 2020In this paper, we present new phase-shifting algorithms (PSAs) that suppress the ripple distortions and spurious pistons in phase-shifting interferometry. These phase errors arise when non-uniform phase-shifting interferograms are processed with PSAs that assume uniform phase shifts. By modeling the non-uniform phase shifts as a

Design of a Compact Hairpin Filter with Spurious Suppression
Journal of Electromagnetic Waves and Applications, 2011In this paper, a new method for suppressing the first spurious passband in microstrip hairpin filter is proposed. For this purpose, meandered shaped coupled lines are used instead of conventional coupled lines. Furthermore, by using this method, a size reduction of 50% is achieved.

Spurious modes suppression in Stacked Crystal Filter
2010 IEEE Long Island Systems, Applications and Technology Conference, 2010Stacked Crystal Filters (SCFs) are used in Bandpass filters and other applications where frequency control is required. SCFs use the Solidly Mounted Resonator (SMR) structure to enable operations at RF frequencies, typically 1–5 GHz. In the response spectrum of the SCFs, besides the main resonance mode, there are some unwanted additional modes present ...

Suppression of spurious signals in thermal MEMS gyroscope
2012 IEEE Sensors, 2012This paper proposes a way of suppressing the confounding effect of acceleration and gravity on the measurement of rotation by the thermal MEMS (Micro-ElectroMechanical Systems) gyroscope [1]. Gravity, like acceleration, induces convection currents within the device, and the position of these convection currents changes as the two heaters within the ...

Suppression of Spurious Modes in FBAR-Resonators
2007Bandpassfilter aus FBAR-Resonatoren haben das Potenzial, die hohen Anforderungen aktueller und zukünftiger Mobilfunksysteme zu erfüllen. Durch ihre maximale Arbeitsfrequenz von etwa 10GHz und eine gute Temperaturstabilität bieten sie eine Alternative zu etablierten mikroakustischen Filtertechnologien.
