At Knowles, we are well known for our expertise delivering high-performance mmWave filtering options.

Ripple current generates heat inside capacitors, making proper capacitor selection, derating, and thermal management essential for long-term reliability in power electronics.

Knowles’ compact ceramic filters help modern satellite communication systems achieve precise frequency control, lower interference, and high performance in space- and weight-constrained applications.

AI datacenters are pushing power demands higher, making advanced capacitors essential for efficient, stable, and scalable power delivery.

Knowles Balanced Armature technology helps power Motorola’s new moto buds 2 plus, delivering premium hybrid audio with exceptional clarity, and detail.

A quadrature hybrid coupler splits a signal into two equal outputs with a 90° phase difference while improving load matching.

As the demand for faster communications across consumer and commercial devices continues to increase, operating frequencies of RF devices are being pushed higher and higher.

Knowles’ new multi-way balanced armature drivers simplify IEM design while delivering premium, customizable audio performance.

The Wilkinson Power Divider, designed by Ernest Wilkinson in the 1960s, uses quarter wave transformers to split an input signal into two equal phase output signals. Since the design is reciprocal, Wilkinson Power Dividers can also be used as a power combiner. With this flexibility, they are widely used in many RF and microwave communication systems, including those with multiple channels or complex feed networks.

Today’s power grids are under increasing strain, from rising instability and greater electrification demands to the rapid expansion of renewable energy sources. Together, these pressures are creating an urgent need for more resilient and responsive power distribution architectures.

Radio frequency (RF) power dividers are designed to split an incoming signal into multiple outputs such that there’s a portion of the original signal’s power in each output. Given their critical function, power dividers play a particularly important role in antenna systems, telecommunications, and signal processing.

Power electronics play a critical role in converting and managing electrical energy efficiently. As electric vehicles (EVs), renewable energy systems, and consumer electronics quickly become more powerful, the demand for high-voltage power electronics is quickly increasing. This means the importance of components like bootstrap capacitors has grown significantly.
