by Ken Ghadia, Sales Engineer, TechnoTronix Radio Frequency (RF) PCBs are very high-speed circuits operating at frequencies in the range of 100MHz and above, typically from 500MHz to 2 GHz. RF PCBs are the backbone of wireless networks, high-tech gadgets like smartphones, smart TVs, etc. Also, RF PCBs are used in automotive, medical equipment, military, […]

Optical links for spacecraft, Part 1: The throughput limitation
Using laser-sourced light beams rather than wireless RF to link spacecraft with Earth offers the possibility of a significant increase in data rates. Still, there are significant technical challenges to the concept. Scientists, engineers, and researchers communicating with spacecraft have a problem: there’s so much data coming from these spacecraft – and to send to […]
Front-haul ICs drive 50 Gbps PAM4 5G wireless optical modules
Semtech Corporation announced sampling of the newest member of its Tri-Edge CDR portfolio, the GN2256. Integrating Semtech’s proven Tri-Edge CDR platform with a differential EML (Externally Modulated Laser) driver, the GN2256 is the industry’s first such IC solution to enable 50Gbps PAM4 Fixed-WDM (Wavelength Division Multiplexing), Tunable WDM and Silicon Photonics optical modules. As with all […]
Synchronizer, attenuators added to RF timing portfolio for 4G/5G radio
Renesas Electronics Corporation expanded its communication timing portfolio with three new low phase noise, high-frequency RF timing solutions for 4G and 5G radio, and two new Winning Combinations to address the need for full signal chain solutions. The new 8V19N850 radio synchronizer and 8V19N880, 8V19N882 JESD204B/C clock jitter attenuators deliver ITU-T compliant network clock synchronization, […]
Metamaterials for power and energy
The first two FAQs in this series considered the potential for metamaterials to have significant impacts on advanced optics, audio systems, thermal management, and various aspects of mmWave communications and radar. This final FAQ will consider the impact metamaterials are expected to have on energy harvesting (both solar electric and solar thermal) high-power long-distance power […]
RF/Microwave bandpass filter implementations, Part 2: Cavity and comb filters
The well-known and extensively analyzed lumped-element bandpass filter is generally not suitable for the RF/microwave region, but there are many distributed-element, energy-based alternatives. Part 1 of this article established the context for these RF/microwave filters, which operate in the spectrum from several hundred MHz and higher, and increasingly cannot use discrete lumped-circuit elements (RLCs). Instead, […]
RF couplers cover 26.5 GHz to 67 GHz range
Fairview Microwave Inc., an Infinite Electronics brand, has debuted a new line of high-frequency couplers that are ideal for point-to-point radios, 5G telecommunications, satellite communication, automotive radars, and aerospace applications. Fairview’s new series of high frequency RF directional couplers is comprised of 24 new models that deliver excellent isolation, low insertion loss, and very good return […]
Technology boosts on-board antenna performance up to 2 dB
New technology is said to deliver significantly better antenna performance. This innovation is particularly suited to designs with shorter ground planes, allowing IoT and other device designers to field a wider range of smaller devices that would otherwise not have been able to meet certain stringent carrier certification requirements. Taoglas Boost uses a new technique […]
First embedded PIFA antenna for Wi-FI MIMO apps
Laird announced the FlexMIMO – the industry’s first flexible PIFA antenna for Wi-Fi MIMO applications. The FlexMIMO has two integrated 2.4/5 GHz dual-band antenna elements specifically designed for 802.11 MIMO applications, such as automated equipment, medical devices and a myriad of Internet of Things (IoT) use cases. The FlexMIMO is based on a Planar Inverted-F Antenna […]
Thin band-pass filters span 620 to 5,930 MHz range, features low insertion loss
AVX Corporation has released a new series of low-profile, high-performance band-pass filters based on AVX’s patented and proven multilayer organic (MLO) high-density interconnect technology. The new BP Series MLO band-pass filters incorporate high-dielectric-constant and low-loss materials that are expansion matched to most organic PCB materials, providing improved reliability over standard silicon and ceramic devices, feature an […]
