Link Microtek has designed and produced a compact high-power 9-way radial combiner specifically for BAE Systems as part of a program to upgrade customers’ S-Band radar transmitters by replacing their magnetrons with multiple solid-state power amplifiers (SSPA).
EM Solutions Cobra M2 Maritime SATCOM Terminal has successfully completed the WGS testing and certification process and been notified by the certification authority that the terminals are now able to operate at Ka-Band on the WGS Satellite Network.
Lockheed Martin Skunk Works® and DARPA recently performed a series of flight tests demonstrating how a SoS approach enables seamless–and rapid–integration across air, space, land, sea and cyber in contested environments.
Akoustis Technologies announced its first production order for initial quantities of a 3.8 GHz BAW filter. The order, from a “well-established military OEM,” is the company's first BAW filter design win above 3 GHz.
The FCC has adopted a Notice of Proposed Rulemaking (NPRM) proposing flexible use for 500 MHz of mid-band spectrum between 3.7 and 4.2 GHz. Seeking to allocate spectrum for new wireless uses while treating existing users fairly, the FCC asks Fixed Satellite Service (FSS) earth stations operating in the band to certify the accuracy of their existing registration and license information, part of the commission's effort to understand how the band is being used.
VadaTech announces the AMC587 and AMC588. These modules couple high-performance RF front end with an XCVU13P providing signal processing bandwidth at over 20 TeraMACs of DSP compute performance in the compact AdvancedMC (AMC) form factor.
SemiGen announces new foundry capabilities and hi-rel screening services. Now offering wafer processing of 100 to 150 mm silicon wafers, as well as alumina and aluminum nitride substrates up to 4.25 in.
We will first present an overview of phased-array antenna fundamentals and basic Active Electronically Scanned Array (AESA) principles and challenges, and then we will explain how planar solutions can help with form-factor issues. We will also show how planar solutions at frequencies at or above X-band require increased integration, as well as highlighting some associated challenges.
Electronic Warfare Fundamentals Poster.Â This poster contains a radar warning receiver and DRFM based jammer block diagrams, a compare and contrast of Radar versus EW, basic equations, cross-eye jamming, modern jamming techniques, three areas of EW; common acronyms and the latest hardware and software for electronic warfare test and measurement.
Pulse signals are widespread in radar and other EW applications and must be accurately measured for manufacturing, design of countermeasures, and threat assessment. However, pulse measurements are an especially challenging area for signal analysis due to a combination of factors such as wide pulse bandwidth, pulses that are difficult to detect, and increasingly complex signal environments. This application note discusses the best tools for different types of pulse analysis, along with display and analysis techniques for various signals and measurement goals.
For decades, spectrum analyzers have been used to develop and characterize radar and electronic (EW) warfare systems. However, traditional swept measurements are rapidly becoming insufficient because most modern radar systems are adaptive. Learn about methods for monitoring EW scenarios, identifying unwanted events in the transmitted waveform, and accurately measuring found signals.Ã?Â
This White Paper provides a view on radar waveforms for Aerospace and Defence and commercial radar systems. Waveforms such as pulse and pulse-Doppler signal, continuous wave and frequency shift keying waveforms are described. It also shows continuous waveform trends designed for specific needs and application differences of continuous wave radar compared to pulse radar systems.
The Defense Industry is facing many challenges. From shrinking budgets to Better Buying Power 2.0 to increased competition for program wins. And, for applications that rely on RF and microwave technologies, the supply base is highly fragmented resulting in increased costs and risks for prime contractors. Mercury is pioneering open architectures for RF/Microwave solutions and has implemented a concept around Advanced Microelectronics Centers (AMC) to provide the design, manufacturing and testing capabilities needed to deliver on key program needs. This whitepaper discusses why open architectures will be a game changer in RF/Microwave and what makes the AMCs unique and relevant.
This application note describes typical satellite applications that require power measurements and recommends power measurement solutions. It also explains how these solutions can help simplify your work, and improve accuracy, reliability and test coverage. Also covered are new sensor functions such as built-in Gamma and S-parameter corrections and real time measurement uncertainty calculations for improved accuracy.
This application note provides an overview of field testing radar systems and Line Replaceable Units (LRU) using high-performanceÃ?Â FieldFox combination analyzers having multiple measurement modes including a peak power analyzer, vector network analyzer, spectrum analyzer and vector voltmeter. This application note will show several measurement examples of pulsed and secondary radar signals and also reviews the basics ofÃ?Â monopulse radar.
