Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. The following example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth. The geometry for the house was imported from a CAD file and a flat terrain was placed underneath the house.
Choosing the appropriate amplifier for a system is vital for the system’s total performance. While there are many different characteristics of power amplifiers, this article focuses on an amplifier’s linearity and when it is important to consider in a selection process.
In order for a receiver to properly demodulate an RF signal and recover the data, the signal that arrives at the receiver must be sufficiently higher than the noise. This task can be accomplished with a Low Noise Amplifier (LNA). This article presents the different benefits of using an LNA and how this instrument can improve wireless systems.
Gowanda Electronics is proud to introduce the Gowanda ER3013 series; the industry’s first off-the-shelf RF Surface Mount (SMT) Inductors with established reliability (ER) rating. This series is designed to enable faster assembly processing and reduce the cost of high-reliability electronic systems where ER components are utilized, making designs attainable for even the most challenging high-reliability components.
NuWaves introduces the Multi-Octave Radio Frequency (MORF) Up-Converters covering the HF, VHF, and UHF bands, as well as the L- and S-bands. Ideal applications include frequency conversion, signal generation, and system integration.
NuWaves introduces the High Intercept Low Noise Amplifier (HILNA) series of amplifiers ideally designed for applications requiring low noise and high linearity.
This video introduces the many different engineering services that NuWaves has to offer, including RF telemetry, RF stealth and signal exploitation, RF systems and subsystems, as well as research and development.
The Convertawave 2 is an RF downconverter designed to be tuned across the 200 MHz to 2.5 GHz frequency range, and can intercept signals in the VHF, UHF, L-band, and S-band providing a filtered IF frequency output of 70 MHz.
This webinar addresses issues and challenges users face when monitoring the spectrum in complex environments, how software-defined radio can overcome these challenges, and changes to the spectrum monitoring landscape.
