Knowles Precision Devices

As many aerospace and defense and satellite communication applications face new requirements to perform increasingly complex tasks with unwavering precision and reliability, the wider bandwidths and faster speeds available in the millimeter wave (mmWave) portion of the RF spectrum are becoming increasingly attractive.   

Wilkinson Power Divider’s are widely used in many RF and microwave communication systems, including those with multiple channels or complex feed networks. Learn more about how Wilkinson Power Dividers work and how they play a crucial role in overall device performance.

For every mission-critical application, the space qualification and screening process is unique. Download our new white paper to learn more about the common standards and testing processes that will help ensure components are designed to operate reliably in challenging space environments.

The spectral environment is quickly changing today. It’s becoming more crowded, which is resulting in an increase in spectral noise. This is presenting a variety of new challenges for RF designers, both in terms of the architecture and power needed to transmit and receive signals and the types of jobs filters need to perform in receivers (Rx) and transmitters (Tx).

RF front-end architectures grow more complex with each generation of communication systems. To accommodate these architectures, more densification and miniaturization is taking place with electronic systems implemented through innovations in system-in-package (SiP) design. Cadence offers the broadest, most integrated design solution to bring the Intelligent System Design™ strategy to the communication products of the future.

In this paper we discuss a commonly asked question, “Why not just integrate a filter in the board stack?” Besides overall filter performance concerns, our answer to this comes in two parts: First there are manufacturing tolerances to consider, and second there is size.

Frequencies in the mmWave spectrum will play a key role in 5G communications. RF technology that was developed around existing mmWave applications has evolved to encompass the needs of 5G wireless access.

The white paper reviews basic microstrip topologies and covers the various types of structures used in filter designs. The advantages and disadvantages of each are covered to understand the important tradeoffs that occur with each filter type. It provides the critical information you need to know to work closely with a filter company to design appropriate filters for your needs.
