Objective: The objective of this activity is to study, manufacture and test filters based on Thin Film Bulk Acoustic Resonator (FBAR) technology at frequencies up to C-band.
Targeted Improvements: Considerable footprint (up to 50%-70%) and mass reduction when compared to current filter technology, enabling the next level of miniaturised microwave modules.
Description: Surface Acoustic Wave (SAW) filter technology has proven to be very successful in many telecom applications both in space and on ground. This type of technology offers very small devices with high performances. However, the frequency range is limited to around 2 GHz due to process limitations, which together with a power loss that may be very high, is preventing a more widespread usage.
Film Bulk Acoustic Resonator (FBAR) technology has potential for application at higher frequencies, lower power losses and wider bandwidths. It is the result of the combination of microelectronics techniques with the well-known technique of bulk acoustic wave filters. The small size of the device and new material have shown in a C band demonstration filter.
This technology is a key technology for miniaturization of microwave modules with a significant improvement in terms of integration density.
Hence the activity aims at assessing filters based on thin Film Bulk Acoustic Resonator (FBAR) technology at frequencies up to C-band for telecom applications. This shall include evaluationof concepts for implementing multiple transmission zeros and accurate simulation techniques.
The work logic is as follows:
In a first Phase, the existing technologies shall be reviewed and a manufacturing concept shall be validated through the fabrication of simple demonstrators. Preliminary designs of the demonstrators shall conclude this Phase.
In a second Phase, FBAR filters shall be designed, fabricated and measured against agreed specifications.
