Medical speakers meet alarm signal requirements of IEC 60601-1-8
CUI Devices’ Audio Group announced a new line of medical speakers designed to meet the alarm signal requirements of IEC 60601-1-8. The CDSM and CMSM models feature resonant frequencies up to 400 Hz and a smooth frequency response with fluctuations no more than ±15 dB, making them ideal for supporting IEC 60601 medical designs. Available with a variety […]
What is immersive audio and how does it work?
Immersive audio extends conventional surround sound technology into the third dimension. It adds height and more to the audio experience. This FAQ presents some of the basic concepts of immersive audio, looks at how ambisonics relates to immersive audio, and closes by looking at a new recommended immersive audio system design practice. Immersive sound transforms […]
PC-specific audio device combines smart amplifier and low-power codec
Cirrus Logic announced today a premium audio solution built specifically for PCs that enables a louder, more immersive audio experience, whether listening to voice calls and music from the small internal speakers on ultrathin laptops or from headphones. Cirrus Logic’s PC-optimized audio solution includes the Cirrus Logic CS35L56 smart amplifier packed with processing power to […]
Zero-drift amplifiers finesse ultralow-frequency signals, part 1
Modern zero-drift amplifiers provide the extremely low drift and noise performance needed for processing many optical biological, and physical-world signals near 0 Hz. In our world of ever-faster, wider-bandwidth signals and systems operating at higher and higher frequencies, it may seem that signals in the very-low-frequency range — down towards zero hertz (0 Hz) — […]
Swapfest: The 2023 season opener
Cambridge, Mass. — On a cold, wet, windy day about two weeks after baseball season opened, the 2023 Swapfest: The Flea at MIT season opened. Ocurring on the third Sunday morning of the month through October, the swapfest isn’t so much for swapping, but more for buying and selling. While I didn’t buy anything on […]
Broadened amplifier line covers VHF, UHF, L, S, C, X and Ku bands
Pasternack has broadened its line of high-power amplifiers engineered for a wide array of market applications in VHF, UHF, L, S, C, X, and Ku bands. This new series of high-power amplifiers provides saturated output power levels ranging from 10 watts to 200 watts and is designed with rugged, military-grade, coaxial packages with an operational temperature range from…
From resistors to antique radios, swapfests have it all
Multifunction GaAs pHEMTs target 100-GHz apps
WIN Semiconductors Corp. has released its newest 0.1µm pHEMT technology: PP10-20. Building on the proven PP10 platform, this second-generation technology offers a substantial transistor gain, improving the ƒt/ƒmax to 160GHz and 240 GHz. These improvements maintain the reliable 4V operation necessary for backhaul power amplifiers and high linearity receivers operating from W-band through D-band. Targeting […]
Amplifier boosts signals from 2 GHz to 18 GHz
The AM1111 amplifier from Atlanta Micro provides 16 dB of gain from 2 GHz to 18 GHz. You can cascade multiple amplifiers to boost signals as needed. Powered by +5 V and packaged in 3 mm QFN package, the AM1111’s input and output provide a 50-Ω DC-blocked impedance.It consumes 500 mW and has a 2.5…
