Even AuSIM's audio simulation is only as good as the model parameters within the simulation. For AuSIM, deriving optimal model parameters begins with studying the acoustic world around us. The AuSIM3Dtm display systems synthesize a virtual aural environment from parameters based on the physical world. But the same techniques can be applied to reverse the process and extract parameters from the physical world to use for later synthesis.

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.
