mmWave antennas and antenna management for 5G
Antennas, antennas, and more antennas are one of the keys to successfully developing 5G new radio (NR) devices employing millimeter wave (mmWave) bandwidths. 5G NR handsets are highly complex devices. They have to handle the new 5G mmWave bands, including 4×4 multiple input and multiple output (MIMO) antennas, 3GPP specified Evolved Universal Terrestrial Radio Access […]
Automotive antenna-on-package mmWave radar sensor features 1-in-cube form factor

What is the 5G RF/mmWave signal chain?
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 […]
Wireless testbeds support new WiFi 6E standard
The Pal-6E wireless personal testbeds now support Wi-Fi 6E. A massive portion of new spectrum is made available by regulators around the world for Wi-Fi and other unlicensed uses. A total of 1,200 MHz in the new 6-GHz band increases the number of 80 MHz channels available for Wi-Fi from six to twenty resulting in […]
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 […]

What are RF inductors?
Radio frequency (RF) inductors have several uses and are available in various construction types to suit the performance needs of specific applications. Matching, resonators, and chokes are common uses for inductors in RF circuits. Matching involves eliminating impedance mismatches and minimizing reflection and losses in the lines between circuit blocks such as the antenna and […]
