Bulk Acoustic Wave (BAW) filters owe their performance advantages particularly to the excellent Q?vaules of the acoustic resonators. As these devices achieve very low impedances in the series resonance condition, the ohmic conductivity of the electro

Bulk acoustic wave (BAW) and FBAR technologies offer key advantages for transmit filters which are used between the power amplifier and antenna in cell phone applications. The classical challenge for Tx filters in duplexers is to achieve low insertio

RF filters for GPS receivers inside phones require extreme stopband attenuation in order to protect the weak GPS signals from interference by the cellular phone bands and ISM bands. In contrast to RF filters for cellular phone bands which typically r

The challenge for developing a duplexer for US-PCS mobile phones comes from the close proximity of TX and RX pass bands as well as from very stringent rejection and isolation requirements. Until recently, only rather bulky ceramic filters were able t

RF-MEMS filters such as Bulk-Acoustic-Wave (BAW) filters are determined to replace conventional RF-filters in mobile communication as they have demonstrated performance and size advantages and can be manufactured at very low costs. Key performance pa

A new general purpose approach for a sensor based on a mass-weighting principle has been developed. This concept offers the advantage to replace a complex and expensive optical system by a low-cost electronic readout system. In contrast to all establ
