What is passive intermodulation?

July 23, 2021 By Jeff Shepard

PIM setup

Passive intermodulation (PIM) is a pernicious and destructive phenomenon for cellular network operators. PIM shows up as a set of unwanted signals created by mixing two or more strong RF signals. Mixing generally produces the sum and difference frequencies of the two transmit signals F1 and F2. These signals are F1 + F2 and F1 […]

The single-chip loudspeaker: First fully MEMS-based speakers target earphone apps

July 7, 2020 By Lee Teschler

What is billed as the world’s first monolithic true MEMS speaker is just one millimeter thick and is said to deliver high fidelity, full-bandwidth sound and low total harmonic distortion (THD) for sealed in-ear personal audio devices, including true wireless stereo (TWS) earbuds. Called Montara by its creator  xMEMS Labs in Los Altos, Calif., the […]

4 μA accelerometer extends battery life in wearables and IoT applications

January 15, 2018 By Aimee Kalnoskas

At the 2018 Consumer Electronics Show (CES) in Las Vegas, USA, Bosch Sensortec launched the BMA400, an ultra-low power acceleration sensor for wearables and Internet of Things (IoT) applications. The BMA400 draws ten times less current than existing accelerometers while delivering solid high performance. Its greatly reduced power demand significantly extends battery lifetime, especially on […]
