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 ...

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 ...

Nautel will offer two in-depth paid training sessions this year, to be held at the company’s new training center in Hackett’s Cove, Nova Scotia. Courses will be in June and September. Each will last ...

Abstract: This tutorial presents an overview of RF and mm-wave power-amplifier (PA) designs in silicon, focusing on the design fundamentals. First, the tutorial introduces PA performance metrics and ...

Often underestimated, RF field probes are critical to the implementation of a proper radiated immunity test system. All too often, system specifiers gloss over this essential element after having ...

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 ...
