Take a journey around a Smith chart to find capacitance and inductance values in a matching network. Before computers became ubiquitous, the Smith chart simplified calculations involving the complex impedances found in RF/microwave circuits such as the one shown in Figure 1. That circuit includes a source with impedance Zs, transmission line with characteristic impedance […]

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 […]
Test gear checks out Wi-Fi 7 chipsets
An automated test solution checks out Broadcom Wi-Fi 7 chipsets, the industry’s first Wi-Fi 7 chipsets optimized for mobile handsets that also support simultaneous dual-band 2×2 IEEE 802.11be-compliant operation. Rohde & Schwarz collaborated with Broadcom to successfully verify the R&S CMP180 next generation wireless device test platform for R&D and production. The IEEE 802.11be amendment […]
Temperature-compensated RF amps cover 0.5 GHz to 40 GHz
A series of temperature-compensated amplifiers address precision performance and test-and-measurement applications. Fairview’s new series of coaxial packaged, temperature-compensated amplifiers covers broadband and ultra-broadband frequencies ranging from 0.5 GHz to 40 GHz. Designs incorporate pin diode attenuation circuitry that senses and adjusts broadband gain levels and maintains a minimum gain level of 35 dB over the […]
Ultra-wideband, omnidirectional antennas optimized for radial isotropic measurements from 150 MHz to 18 GHz
Aaronia OmniLOG PRO Omnidirectional Antennas are compact, ultra-wideband omnidirectional antennas suited for radial isotropic use from 150 MHz up to 18 GHz, encompassing most RF sources such as LTE, GSM, UMTS, WLAN, etc. These cost-effective antennas are specified for 1 W cw receive and 100 W cw high-power transmit, making them candidates for broad-range spectrum […]
IMS 2022 video: Test equipment
Several test equipment companies demonstrated their latest products for attendees of the International Microwave Symposium.
Exceeding 100 Gbps with a sub-terahertz 6G testbed
Here’s a look at testing necessary for super-high throughputs involved in the emerging area of 6G. Greg Jue, Keysight Technologies 6G research is in its early stages. The vision for what the International Telecommunication Union calls Network 2030 continues to take shape. While the industry is years away from starting the standards development process, subterahertz […]
Radio altimeter flight-line test set adds fiber optic delay
The ALT-9000 universal radio altimeter (RADALT) flight line test set adds fiber optic delay to traditional radio frequency (RF) testing, enabling it to test all types of RADALTS on the market today. The RADALT measures an aircraft’s altitude above the terrain, by transmitting a radio frequency (RF) signal down to the ground and receiving a […]
Test system handles latest Wi-Fi 6E devices
A newly integrated testing system allows testing to the new IEEE 802.11ax WLAN standard. The new band adds to the already available 2.4 GHz and 5 GHz bands. Anritsu’s Wireless Connectivity Test Set MT8862A has been integrated with the EMITE E600 Reverberation Chamber, allowing developers to test the OTA TRP/TIS performance of IEEE 802.11ax devices […]
Wireless system supports Wi-Fi 6, 6E OTA tests
ETS-Lindgren’s EMQuest software now supports the most current versions of Wi-Fi while maintaining backward compatibility.
