What is a Smith Chart and why do I need one? (Part 1)
A Smith chart provides insight into RF/microwave designs. Even if you work primarily with low-speed analog and mixed-signal designs, you could benefit from familiarity with the Smith chart as wireless products proliferate and as high-speed-serial data signals exhibit microwave-like effects. When a signal’s wavelength (λ) approaches the lengths of the conductors carrying it, you can […]
SP4T RF switches now available in production quantities
pSemi Corporation announces the production readiness of two new high-linearity switches targeted for the latest 5G wireless infrastructure and massive MIMO base station deployments. By using the new high linearity switches in hybrid architecture topologies, base station designers can save valuable board space and improve thermal management, reducing the overall system’s cost, weight, and power…
Video: Wi-Fi 7 operates across frequency bands
In a video interview, Wi-Fi test veteran Fanny Mlinarsky updates us on Wi-Fi 7’s new features and how they work.
Waveguide horn antennas cover frequencies to 40 GHz
Pasternack has just introduced an innovative series of in-stock, waveguide horn antennas that can be used in a wide variety of wireless applications. Pasternack’s new line of waveguide horn antennas provides wide frequency coverage from 1.7 GHz to 40 GHz and with a low VSWR of less than 1.3. They demonstrate highly efficient radio-frequency power transmission.…
Hinged antenna connection IoT devices to low-frequency LTE bands
Linx Technologies (Linx) introduces the ANT-450-HSW, a monopole whip-style antenna for cellular and cellular IoT applications in the 410 MHz and 450 MHz bands, including LTE bands 31, 72, 73, 87, and 88. The latest release from Linx is especially well-suited for metering, utility, industrial, and Internet of Things (IoT) devices. The hinged design of…
Power management device target low-Earth orbit space applications
Microchip Technology Inc. announces the introduction of its first commercial-off-the-shelf (COTS) rad-tolerant power device with the MIC69303RT 3A Low-Dropout (LDO) Voltage Regulator. The new high-current, low-voltage MIC69303RT is a power management solution targeting LEO and other space applications. The device is available for prototype sampling in both plastic and hermetic ceramic to support the requirements […]
Cellular LTE modem achieves Verizon certification
Janus Remote Communications is announcing it has achieved Verizon certification for their CellBridge LTE910XFX v1.00 Cat1 “X” Footprint (XF) Embedded Cellular modem. The LTE910XFX v1.00 CAT1 embedded modem uses the Telit LE910C1-WWXD as its cellular engine. The LTE910XFX v1.00 units operate in CAT1 LTE 4G, 3G, and 2G bands and are qualified for worldwide operation…
Demonstrating antenna diversity, Part 1: The challenges
Antennas come in abroad range of sizes, styles, and configurations to meet frequency, bandwidth, directivity, and many other objectives; the PIGA and Yagi antennas are rather different yet widely used versions. With a few highly specialized exceptions, all antennas in general use – ranging from tiny ones in wearables to huge broadcast-transmitter designs – are […]
Add-on board enhances precision position data
MikroElektronika has launched GNSS RTK 2 Click board, a compact add-on board used to enhance the precision of position data derived from satellite-based positioning systems. Click boards follow a modular prototyping add-on board standard invented by MIKROE, which revolutionizes the way users add new functionalities to development boards. Click boards enable design engineers to change peripherals […]
