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 ...

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 ...

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, ...

A typical precision operational amplifier (op amp) may have a 1 MHz gain bandwidth product. Theoretically, you might expect RF signals that are in gigahertz to be attenuated to very small levels ...
