How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G mmWave and MIMO systems. This paper presents ten cues that your organization may need a channel modeling tool like Wireless InSite to supplement your 5G network planning efforts.
An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. The AF varies with frequency at the same presented field strength, but at a different frequency, the produced voltage at the connector is not constant. This white paper explains the process of creating AF data and how to use it.
Many products incorporate electronics and wireless communications and need RF interference testing. This requires shielding enclosures that need proper testing to ensure their correct operation.
The US Marines' “mega-drone" is intended carry the same payload as an F-35B and fly a radius of up to 700 nautical miles at 30,000 feet. This Marine Air Ground Task Force Unmanned Aircraft System-Expeditionary (or MUX, for short) also will be able to fill “an extremely broad range of missions."
This white paper focuses on the time domain analysis displays generated from vector network analyzers (VNAs). The paper will also cover frequency domain basics, an in-depth overview of how a time domain display is created from frequency domain data (S-parameters), and steps for applying the time domain display to common problems in RF systems.
KRYTAR’s new directional coupler is a superior performance narrow band product covering the 7.0 to 12.4 frequency range. Adding to the selection of multi-purpose, stripline designs that exhibit excellent coupling, Model 120706 enhances the product line with performance ratings including Nominal Coupling (with respect to output) of 6 dB, ±0.5 dB, and Frequency Sensitivity of ±0.30 dB.
NuWaves Engineering offers the NuFilter™ series of cavity filters designed for applications operating within the 1 GHz to 20 GHz frequency range. Options for standard and custom models include 3 dB bandwidths from 3% to 28%, stop-band rejections of 80 dB, insertion losses of < 1 dB, and up to 50 W power handling (higher power ratings available upon request).
FEKO, Altair’s comprehensive electromagnetic simulation software suite, can be used in electronic virtual prototyping and simulation driven designs, including antenna design for many products such as mobile phones, tablets, cameras, laptops, and TVs. The software can eliminate weak antenna designs and reduce the number of prototypes with its proof of concept and comparative studies. Pre-compliance of over-the-air (OTA) radiation performance and specific absorption rate (SAR) can be estimated for the standalone device, or for different usage environments.

High peak-to-average power ratios (PAPRs) are not beneficial as they challenge the non-linear power amplifier operation close to compression in order to reach maximum efficiency. Possible solutions for include crest factor reductions (CFR), such as clipping high signal peaks. This video demonstrates a simple technique to clip any waveform, including the Verizon Wireless 5GTF signal, with the use of software tools for signal generation and analysis.
