10.17.23 -- How Old Is The Universe? No, Really?


How Old Is The Universe? No, Really?

The age of the universe was once thought to be eternal and today, around 13.8 billion years old is the common consensus. A new theory is suggesting the actual age of the universe might be closer to 30 billion years old.

The Increasing Attractiveness Of Mobile Devices As Targets For Cyberattacks

According to the Group Speciale Mobile Association (GSMA), nine in 10 consumers are concerned over smartphone data security and privacy. But how to ensure security in smartphones if they are such an attractive target? The answer is security can never be ensured, but we can make life much harder for hackers by following best practices when it comes to securing smartphones.


Power Indication & Relative Accuracy In Amplifiers

The purpose and scope of this document is to explain amplifier power indication (metering) and typical variations associated with frequency sensitivity and bandwidth. Exodus amplifiers with our display/controller provide many monitoring and control functions. 


The Importance Of Antenna Beamwidth In RF Testing

Understanding antenna beamwidth and how it influences a test environment is critical to accurate and repeatable tests. This article defines antenna beamwidth, explores the antenna beamwidth properties, and explains its importance for compliance testing.

Wide Bandgap FETs Make Regulating High Voltage Simple

Wide bandgap FETs simplify high-voltage regulation, offering improved performance and eliminating the need for a negative rail in comparison to older transistor-based designs.

Booster Amplifiers Maximize Warfighter Situational Awareness

Booster amplifiers, used in support or in place of other technologies, are a cost-effective, SWaP-conscious, and field-proven tool to extend radio communications ranges in tactical situations.

Power Supplies With Fast Switching Frequency Just Got A Lot Safer

In this bandwidth-hungry age of the Internet of Things (IoT), a number of isolated power supply systems need to be efficiently powered, driving a need for cost- and power-efficient solutions. Today, designers must maximize power per volume, and one way to achieve this is with higher-performance power switches.
