10.09.19 -- RF Filtering For 5G Millimeter-Wave Applications

An Introduction To The 5G Frequency Spectrum

5G networks plan to offer a hundred-fold increase in user data rates, which will require growth in bandwidth over what is currently available. This article introduces the 5G spectrum and explores some of the mechanisms behind the increase in bandwidths.

RF Filtering For 5G Millimeter-Wave Applications

Frequencies in the millimeter-wave spectrum play a key role in 5G communications. RF technology that was developed around existing millimeter-wave applications has evolved to encompass the needs of 5G wireless access. However, filtering in 5G applications offers a new set of challenges brought about by the technology available and the characteristics of millimeter-wave systems.

Understanding Microstrip Filter Topologies

Microstrip refers to a type of planar transmission line technology that consists of a conducting strip separated from a ground plane by a dielectric substrate. Entire devices are formed from metallized patterns on the substrate, making microstrip lighter, more compact and more affordable than alternative transmission line technologies such as waveguide.

Tolerance And Size Analysis For Millimeter-Wave Filter Manufacturing

Manufacturing tolerance and size are important considerations when integrating a filter in the board stack. This article examines different 26 GHz filter manufacturing approaches with specific design goals to better understand the importance of tolerance and size analysis.

Reduce Cost And Complexity In 5G Millimeter-Wave Systems With Surface-Mount Solderable Filter Components

Components for millimeter-wave 5G communications systems should be chosen for their performance and cost. Taking a close look at the packaging technology available to implement high-performance filters in a design can save considerable cost and complexity when it comes to manufacturing a new design.
