Depending on temperature range, the SiT7910 Super TCXO from SiTime can attain frequency stability of less than 0.1 ppm. Clock oscillator circuits serve two functions. They provide a clock timing signal for digital circuits such as microprocessors and they keep track of time, often for time-stamping of events. While oscillators for digital circuits typically produce […]

Antennas for cellular, Wi-Fi, Tetra, UHF and GNSS optimized for tram, light-rail uses
Dedicated antennas optimized for light rail vehicles have been launched by HUBER+SUHNER, further expanding its offering to the transport sector. As all transportation market segments look to cope with rising bandwidth demand, rail, light rail, and road vehicles all have different requirements. The SENCITY Tram rooftop antenna range has been developed to provide an all-in-one […]
From designing to operating an RF PCB: The complete guide
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

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 […]
