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.

In this White Paper Knowles Precision Devices takes a closer look at some of the considerations to make when implementing filters for mmWave applications such as 5G NR radios in the 24, 26, 28 and 39GHz bands.
