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 ...

Sponsored by IDT: What should you look for in a good RF gain block for wireless design? Here are some recommendations. What every RF design engineer needs these days is a good all-purpose IC RF ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Marki Microwave has expanded its core amplifier product portfolio with three gain block amplifiers that serve as key components for a complete RF subsystem. The ADM-8622PSM, ADM-8625PSM, and ...

A class-A amplifier is defined as an amplifier that is biased so that the output current flows at all times. Thus, the input signal-drive level to the amplifier is kept small enough to avoid driving ...

Mouser Electronics is stocking a 5G linear RF amplifier from Qorvo. QPA9822 is designed for 32-node mMIMO (massive multiple-input and multiple-output) antenna systems found in wideband 5G NR (new ...

ADL5580 is a SiGe dc to 10.0GHz differential-in differential-out gain block from Analog Devices, which has a digital bus for signal path tweaking. “The amplifier offers a referred-to-input noise ...
