In a series of experiments conducted last month, Cambridge researchers experienced weightlessness testing graphene’s application in space.
For the first time, astronomers have detected a signal from stars emerging in the early universe. Using a radio antenna not much larger than a refrigerator, the researchers discovered that ancient suns were active within 180 million years of the Big Bang.
Satellite antennas knitted from wires thinner than hair are being developed by Nottingham Trent University for use in outer space.
Physicists at the University of Texas at Austin and City University of New York have developed a fully passive isolator consisting of coupled nonlinear resonators to propagate microwaves over a broad bandwidth. The design could be transferred to optical applications, as well.
Microwave radiometric sensors are devices used to detect electromagnetic energy. This white paper expresses the reasoning for certain radiometer calibrations and other modes of operation in regards to the sensor’s subsystems.
Capacitors are a fundamental building block for RF and microwave systems as they are often used to create filters, generate DC protection, and build bypass networks. Designers often use approximate equations to predict capacitor values and find the final RF performance. However, as a system constantly requires higher performance levels, these assumptions are no longer valid. This article discusses how to improve RF performance by using fewer capacitors that block DC and pass AC current, and how to choose these capacitors based on real world performance.
At shopping malls, consumers also are able to find various types of entertainment, dining options, spa services, childcare, etc. This white paper presents DeltaNode’s Distributed Antenna Systems (DAS) solution for meeting these wireless communications difficulties.
Measuring RF power in a field environment can be accomplished accurately and inexpensively. It also involves a great deal of care and proper training to ensure equipment is accurately measured. Either way, accurate field power measurements will ensure transmitting equipment is operating properly.
Since its invention in the early 1960s, the Rotman Lens has proven itself to be a useful beamformer for designers of electronically scanned arrays. Inherent in its design is a true time delay phase shift capability that is independent of frequency and removes the need for costly phase shifters to steer a beam over wide angles. This article uses the developed software to design and analyze a microstrip Rotman Lens for the Ku band.
It is a reality that in the last decade signature control engineering has received growing attention from worldwide navies. Among these signatures, RCS (Radar Cross Section) is probably one of the most recognized ones, even to the uninitiated, due to its strong visible impact on the shaping of a ship’s superstructure.
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.
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.

The new V Series capacitors deliver increased broadband rejection in a significantly reduced footprint for bypass capacitor filtering networks. Released under the DLI brand from Knowles Precision Devices, this cost-effective capacitor line is built on a compact 30 mil by 30 mil footprint. This superior RF signal blocking design tool will solve the needs of design engineers looking to decouple RF signals from DC bias lines in active circuit designs, such as MMICs, or filter out noise from switching power supplies.
