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 […]
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 […]
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 […]
Dual 5-V op amp sports 50-MHz gain-bandwidth, low input offset voltage, 6.5 nV/√Hz input voltage noise
STMicroelectronics’ TSV792 dual 5V operational amplifier (op-amp) combines 50MHz gain-bandwidth with precision attributes including low input offset voltage and extremely low input voltage noise of just 6.5nV/√Hz. The typical 50MHz gain-bandwidth product enables accurate amplification of high-frequency signals. Adding a fast slew rate of 30V/µs, the TSV792 is suited to photodiode-signal conditioning in battery-powered smoke detectors. […]

The new broadband microwave RF conical inductors from Gowanda Electronics – the C070 – are available in Surface Mount (C070SM) and Flying Lead (C070FL) configurations to enhance utility in the electronics design community, especially for communication applications. The C070 series was developed to address market needs and industry trends calling for ever-increasing performance from broadband […]
Rad-hard 14-bit ADC optimized for apps in space
Renesas is excited to introduce the ISL73141SEH ADC, delivering the industry’s highest performance for radiation-hardened space applications. The ISL73141SEH ADC is one of the key signal-path building blocks in long-duration geosynchronous/geostationary Earth orbit (GEO) communication satellites and manned spacecraft, including lunar space missions. By delivering the industry’s best dynamic and static performance, the new 14-bit […]
WL-CSP 25-W RF switch replaces mechanical relays
Menlo Microsystems, Inc. announced the production release of the MM5130, the first high-performance RF switch manufactured with their proprietary Ideal Switch technology. The MM5130 is designed to handle 25W with ultra-low losses, in a miniaturized wafer-level chip-scale-package (WL-CSP). Historically, this level of performance has been reserved for large RF mechanical relays, which have major drawbacks. […]
DIP switches available in piano, rotary, and slide actuator styles
CUI Devices announced the first launch from their Switches Group with the introduction of a new line of DIP switches. Available in piano, rotary, and slide actuator types, the DIP switches offer 1.27, 2.54, or 5.08 mm pitches, 1 to 16 positions, and surface mount or through-hole mounting styles. These DIP switch models further feature […]
