The Qorvo QPF4209 is an integrated front end module (FEM) designed for Wi-Fi 7 (802.11be) systems. The small form factor and integrated matching minimizes layout area in the application. Performance is focused on optimizing the PA for a 5V supply voltage that minimizes power consumption to allow for systems that use digital pre-distortion to achieve the highest linear output power ...

Distributor Rutronik has added three surface-mount RTK-enhanced GNSS modules from Unicore to its portfolio. RTK – ‘real time kinematics’ – is a service that increases the accuracy of satellite navigation systems.

Kyocera AVX has released low-ESR C0G/NP0 dielectric RF MLCCs (multi-layer ceramic chip capacitors) “inspired by communications market demand for smaller RF capacitors that deliver repeatable performance”, it said. Called KGU, they come in values from 0.1 to 100pF with tolerances as low as ±0.05pF. They come in four chip sizes: 01005, 0402, 0603 or 0805 (EIA). Class I C0G, also ...

Farnell is now shipping the new high-power SPDT (Single-Pole Double-Throw) RF antenna switch from Toshiba. The SPDT RF (TCWA1225G) switch is important for the expansion of 5G networks. This is because the expansion requires antennae that are increasingly composed of complex signal transmission paths that need RF switching with low insertion loss and high input power, but in a compact ...

Toshiba has just released a 700MHz to 5GHz single-pole, double-throw antenna switch in a 1.9 x 1.9mm WCSP package. “TCWA1225G offers an input peak power of 46dBm – at 8dB PAR,” the company said. “This has been achieved by adopting Toshiba’s original CMOS process and optimising the internal switching circuitry.” The process also reduces insertion loss, typically to 0.6dB at ...

A grant from the Pivot into Space programme is funding a Novocomms R&D project to develop a next-gen PNT (positioning, navigation and timing antenna) system for use in space. Pivot into Space is a programme being led by the Midlands Aerospace Alliance. It has funding from the UK Space Agency that is matched by industry. The idea is for the ...

Dr. Ali Sadri considers how some of the limitations for 5G performance can be overcome, for example via RIS and in-building wireless coverage. With the rollout of 5G continuing to cause issues around the globe, some people would argue that it’s not yet living up to the hype. So what’s needed to unlock its potential? Dr. Ali Sadri, CTO of ...

Component distributor Richardson RFPD is stocking a 5 to 8GHz GaAs pHEMT low noise linear amplifier from Guerrilla RF, and has added it to its design support service. Measuring 1.5 x 1.5mm (DFN-6), GRF2110 is aimed at WiFi 6/6E, small cell and wireless infrastructure. It operates from 2.7 to 6V, drawing 70mA at 5V. Power is applied to the output ...

The Z-Wave Alliance has released its 2024A Z-Wave Specification Package, which includes new User Credential Command Class features, as well as new User Credential Control Specifications. These are for managing user credentials within a Z-Wave network. It defines how devices should handle, store, and communicate user credentials such as PIN codes, passwords, or biometric data for secure access control and ...

Taoglas has inset one antenna inside another to cover GNSS L1 and L5 with a 35 x 35 x 4mm surface-mount device – which is optimised for use on a 70 x 70mm ground plane. Designed using a custom electro-ceramics formula, HP5354.A offers “stacked patch L1-L5 performance” within a single patch-in-a-patch solution, according to the company. It “has a passive ...
