Acoustic Emission Sensors
Acoustic wave (acoustic emission) sensors are the ceramic piezoelectric transducers converting the mechanical elastic acoustic waves generated in the material (e.g. elastic waves occur when a material cracks, wears, deforms, or corrodes) to electrical signals. The electrical signals are then amplified and filtered by a preamplifier and then transmitted to a special acoustic emission acquisition instrument for further data processing and analysis.

Bulk Acoustic Wave Technology
BAW
Macom Technology Solutions Holdings Inc.
MACOM’s BAW product portfolio is ideal for high performance Industrial, Aerospace, Defense, and Communications applications that require critical frequency filtering. Our high-performance RF filters enable our customers manage signal integrity in the 1 to 6 GHz frequency range. Bulk Acoustic Wave Resonators consist of two metal electrodes above and below a layer of a piezoelectric material. The piezoelectric material converts an electrical signal to a mechanical signal and vice versa. The metal electrodes provide the connections to/from the piezo material. The frequency at which resonance occurs depends on the thickness of the combined metal-piezo-metal stack. Advances in thin-film piezoelectric fabrication have enabled BAW resonators to meet RF filtering challenges up to 6000 MHz using standard MEMS fabrication process. High-performance BAW resonators-based RF filters are made of piezoelectric material having high Q-factor (>3000) and high coupling coefficient. Currently, no competitive technology provides the same high performance for RF filter applications when compared to BAW resonator-based RF filter up to 6000 MHz for the same size and cost.

COM Express Type 10 Reference Carrier Board
miniBASE-10R
The COM Express approach of custom carrier combined with off the shelf system cores is an excellent solution when you need to customize but lack the time or quantity for a complete redesign. It fits most system integration projects with production volumes from 500 to 10,000 pcs per year. The COM Express concept has a great many advantages over full custom designs, it reduces engineering complexity, lowers the threshold for total project quantity and last but not least brings your product to the market in no time. The average time to design a carrier board is less than half the time of a full custom OEM board.
