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.

Directional Acoustic Transponder (DAT)
The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wide band signals provides far better combined range and arrival angle estimation, especially at low Signal to Noise Ratio (SNR). Our device offers a clear 360 degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.
