The evolution of radar has grown steadily over the decades to its present level that employs sophisticated computerized techniques which has stimulated the development of increasingly complex components. This white paper provides a basic introduction to radar technologies and to the application of radar equipment.
This article explores how industrial IoT can produce real value for electric motors and factories.
Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. This white paper offers guidelines and considerations for determining a divider/combiner for each application.
Noise figure often characterizes a receiver and how well it can detect weak signal sin the presence of self-generated noise. The process of reducing noise figure begins with a solid understanding of the uncertainties in your components, subsystems, and test setups. Keysight Technologies offers ten tips for minimizing the uncertainties in noise figure measurements.
This article describes design of a GaN transistor with internal GaAs input matching. The input matching network is designed for the 2.7 – 3.5 GHz frequency range, making the transistor suitable for S-band radar applications.
MegaPhase offers a series of low loss cable systems made with the industry-leading GrooveTube® design and rugged construction to resist torque, pull, and crush forces. This wide range of connector types may be used in many different markets including phased array radar, electronic warfare, military, and communication systems.
EMI Filters are used to prevent electromagnetic interference in avionics and aircraft systems, as well as military shipboard/vehicle electronics, and in military communication systems. Electromagnetic interference can cause a complete loss of data in communications systems, or a simple decline in data quality.
AR’s “U” Series Amplifiers are designed with the broadest frequency ranges from 10 kHz to 1000 MHz, and offer a wide power spectrum from 1 – 25 Watts. Created with smaller, more affordable sizes without compromising on performance or durability, these amplifiers are ideal for multiple applications across diverse industries.
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.
