Femto/picofarad antenna-tuning ICs enable smartphones to work over several bands and scenarios, thus solving the challenging impedance-matching dilemma. One of the indicators of innovative engineering is to take an attribute that is normally considered to be a drawback and not only negate that characteristic but actually use it to advantage in another setting. Consider this…

When battery life rules, turn off 5G
The data is clear. My phone’s battery charge life looks better with 5G turned off.
Why O-RAN sync monitoring needs AI/ML
As Open RAN deployments gather pace and accurate timing, synchronization has emerged as a critical step toward consistent performance. It is a complex task, with devices requiring time synchronization to UTC reference via IEEE PTP/SyncE-based boundary clocks, slave clocks, PRTC clocks with GNSS receivers, as well as accurate, real-time monitoring in support of customer SLAs.…
How to improve Open RAN security at the hardware level
Open RAN telecom network security begins in the microprocessors that control telecom network equipment. Configure and use these processors with secure booting and build trust.
Crystals for mmWave SoCs feature thermistors
Kyocera has begun mass production of products certified by IC manufacturers and suitable for smartphones compatible with 5G millimeter-wave ultra-high-speed communications, which will be increasingly in demand. Low ESR and stable temperature characteristics are achieved using Kyocera’s outstanding photolithography and plasma CVM technology developed in collaboration with Osaka University (see details here). Available in 76.8MHz, Qualcomm Technologies’ Chipset…
UWB applications bring design decisions
Ultra-wideband communications and location detection applications are steadily increasing. As a designer, you have options and therefore must decide how to best integrate UWB into your IoT design. Impulse radio ultra-wideband, commonly referred to as UWB, is a short-range, wireless communication protocol based on the IEEE 802.15.4z standard, operating at frequencies up to 9.5 GHz.…
Low-loss RF balun family covers 3 GHz to 100 GHz
Fabless mmWave semiconductor startup mmTron Inc. today announced the first four products in a family of broadband, low loss, 50 Ω baluns, covering 3–18, 11–65, and 27–100 GHz. (Baluns are components that transform balanced to unbalanced signals and vice versa.) “Several of our MMIC products use baluns, and we designed our own to get the…
Use TTL or analog signals to program voltage-controlled oscillators
Fairview Microwave has expanded its product line with 15 new analog and TTL programmable voltage-controlled phase shifters. These cutting-edge products cover broad frequency bands ranging from 0.5 GHz to 33 GHz, including the popular market bands VHF, L, S, C, X, Ku, K, and Ka. The new release includes eight models of voltage-controlled analog attenuators…
Embedded antennas cover Wi-Fi bands and more
L-com has just introduced a line of stamped metal antennas. These AP/router-embedded antennas offer a combination of performance, ultra-compactness, and ruggedness. The new omnidirectional stamped metal antennas provide uniform coverage in all directions with isotropic radiation patterns. The signals are optimized with linear polarization and offer a typical gain of up to 5.1 dBi and…
Renesas agrees to acquire Sequans
The acquisition widens the Renesas product line of IoT wireless connectivity modules and adds the chips that go into them.
