Knowles has released the ATT A-Series of attenuators, a new product line engineered for integration into modern radio frequency (RF) signal chains. These components offer broadband performance capable of handling increasing frequency and bandwidth demands.

Why it matters

Modern RF systems increasingly require smaller, more precise components to maintain signal integrity as operating frequencies rise. This new series provides a scalable solution for engineers working with space-constrained circuit designs.

The ATT A-Series components measure 2.03 by 1.65 by 0.30 mm and support broadband performance from DC to 20 GHz. The series features standard attenuation values from 0 dB to 20 dB with 50Ω matched RF inputs and outputs.

The players

Knowles

Knowles is a global supplier of advanced micro-acoustic, audio processing, and precision device solutions for the mobile, consumer electronics, and industrial markets.

The details

Designed for use in compact surface-mount technology (SMT) packages, these attenuators function within an operating temperature range of -55°C to +125°C. They are specifically built to manage up to 6.5 W continuous wave (CW) power at 100°C.

The Tech Race

The introduction of the ATT A-Series reflects the broader industry trend of shrinking component footprints while maintaining high power efficiency in dense circuit boards. These attenuators replace larger legacy modules to support the ongoing race for smaller, more powerful communication hardware.

Engineers and product designers can utilize these compact components to reduce the overall size of wireless communication devices and industrial RF systems. This integration leads to more efficient PCB layouts and potentially smaller consumer electronic devices for the end user.

The takeaway

The arrival of high-performance, miniaturized attenuators highlights the critical role of passive components in modern signal processing. Designers should prioritize these compact SMT solutions when seeking to balance high power handling with the physical constraints of advanced RF architectures.
