The 5G RF/mmWave signal chain is expected to be the same as, and different from, the RF signal chain for today’s LTE Advanced devices. 5G consists of two separate frequency bands, FR1 is mostly repurposed LTE bands and FR2 bands are in the mmWave region. As a result, 5G in the FR1 frequencies can use […]

Basics of mmWave and its applications
The millimeter band spans from 30 to 300 gigahertz (GHz) and lies between the super high frequency band, and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ten to one millimeter; thus, radiation in this band is called millimeter waves, sometimes abbreviated […]
The basics of FR-4 Printed Circuit Boards
Part 1 of this FAQ provided context and background on the PC board, and discussed its first widespread appearance as a phenolic-based board. Part 2 looks at some board issues and the widely used FR-4 PC board substrate. Q: I see the term “solder mask” — what is that? A: Solder mask (also called a […]
Digital Step Attenuators support 5G frequency demands
pSemi Corporation, a Murata company focused on semiconductor integration, announces the expansion of its digital step attenuator (DSA) portfolio with two new high-performance DSAs, PE43610 and PE43614. Featuring industry-leading attenuation accuracy, the PE43610 and PE43614 DSAs support the entire 9 kHz–13 GHz and 9 kHz–45 GHz frequency ranges, respectively. Ideal for 5G test-and-measurement applications, these DSAs exemplify pSemi’s […]
Soft, conformable EMI absorber material doubles as a gap filler
Electronics are getting more compact, yet also more powerful, especially with the rise of 5G. Components packed into tight spaces produce complex signal interference issues, which can hinder device operability in automotive and other industries. But using standard EMI-mitigating absorbers as an interface between a radiating component and housing can put too much stress on […]
Power dividers, directional couplers handle 40 GHz
