RF engineers often need to calculate parameters such as VSWR and RLC networks. Ampleon provides these and other free RF design tools for you to use. Ampleon, a maker of RF components, provides engineers with a free RF online tools page where you can find four sets of useful tools. Each of the four tools […]
Verify, test, and troubleshoot 5G Wi-Fi FWA gateways
By Xiang Li, Keysight Technologies Follow these three steps to ensure your fixed-wireless access designs will be compatible with the Wi-Fi fronthaul and 5G backhaul. Many areas lack the wired infrastructure to bring residential broadband access. Making those connections has become costly and inefficient. Fixed Wireless Access (FWA) has emerged as a compelling alternative to […]

This system is a compact rack-mount solution that includes server hardware, GL MAPS software, and channel banks, with […]
OFC 2024: How AI and silicon photonics will drive network test
EE World spoke with Sarah Boen, Director of Technology and ASIC Strategy at Tektronix, who spoke at a panel session on how AI and silicon photonics are changing networks and the challenges facing test engineers and reliability engineers.
IMS 2024 roundup: test equipment
Washington, DC — The 2024 International Microwave Symposium took place here in June at the Walter E. Washington Convention Center. As always, RF/microwave/mmWave test equipment was all over the exhibit hall. Frequency-domain test equipment — spectrum analyzers, vector network analyzers, power meters, and signal generators — were, of course, dominant. Other equipment, such as oscilloscopes […]
How can I quantify a device’s nonlinearity? part 3
A higher third-order intercept point results in lower intermodulation products at any given input power level below compression. In part 1 of this series, we discussed the 1-dB compression point as a figure of merit for device linearity. In part 2, we examined a circuit that adds two fundamental input signals of frequencies f1 = […]
USB oscilloscopes add automotive 10Base-T1S protocol analysis
Pico Technology, a manufacturer of USB oscilloscopes, has added 10Base-T1S protocol analysis to software that operates the company’s line of USB oscilloscopes. That brings to 40 the number of serial protocols that the company supports. PicoScope 7 software is a free download. 10Base-T1S is a two-wire Ethernet standard that specifies a physical layer for automotive […]
How can I quantify a device’s nonlinearity? part 1
You can specify nonlinearity in parts per million or, especially for RF components, in terms of the 1-dB compression point or third-order intercept point.
What is intermodulation, and is it good or bad? part 4
Nonlinearities in active circuits and passive components can add harmonic and nonharmonic distortion. This series has investigated intermodulation, the process by which the application of two frequencies to a nonlinear system results in the system generating frequencies that equal the sum and difference of the input frequencies. In Part 1 and Part 2, we looked […]
