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.

High Accuracy AC Reference Source
515
Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.

Manikins for realistic simulation of the acoustic properties of a human
Head & Torso Simulators
If you need to carry out realistic in-situ measurements of headphones, telephones or hearing aids, you need a Head and Torso Simulator such as the B&K ‘HATS’ – Type 4128D or GRAS’ Kemar to complete your test setup. These manikins have built-in ear and mouth simulators that provide a realistic reproduction of the acoustic properties of an average adult human head and torso. They are commonly used for tests on telephone handsets, headsets, audio conference devices, microphones, headphones, hearing aids and hearing protectors. Please contact your sales engineer or email sales@listeninc.com for more information.

Series Voltage References
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.
