With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

Wireless communications products that depend on RF principles are everywhere these days, and the growth rate is astonishing. From cell phones and wireless PDAs to Wi-Fi-enabled laptops, Bluetooth ...

Recent advances in high-speed data converters now digitize or generate signals directly at radio frequencies up to several gigahertz, replacing traditional radio-frequency (RF) components like mixers, ...

Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...

For Nautel’s head of customer service, John Wilton, the “aging out” of broadcast engineers is a rising concern. Why? The lack of RF knowledge could put Radio at risk in the coming years. That has led ...

Abstract: Analog radio frequency (RF) systems are complex, involving unfamiliar terms, complicated regulations, and uncommon circuit operations. Additionally, the electronics often deal with a broad ...
