A good integrated synthesizer design is a balance of competing requirements depending on the target application. The CMX940 High Performance RF Synthesizer balances exceptional low noise performance, low power and now, following the publication of a new Application Note, demonstrates extremely fast switching times...
For those familiar with designing RF frequency generation circuits spurs are an unwelcome fact of life. The designer wants to generate a nice clean low noise signal but because of the way PLL’s work and other physical effects, the signal often also has other imperfections...
Cellular telephony has defined the early part of the 21st century and there is now an entire generation that has never known life without the constant companionship of a smart phone. Anticipation for 5G continues to grow...
Many transmitters using non-constant envelope modulation schemes benefit from the improved efficiency and linearity associated with using a Cartesian feedback around the power amplifier. Though the concept of using feedback to linearize an amplifier is straightforward, there are many system elements and parameters that can...
While the Internet of Things is a worldwide wonder that promises to connect everything, it’s probably worth remembering that the study of electromagnetism started nearly 200 years ago and was, in a very real way, the birth of radio....
We live in a world that is increasingly connected and where the need for wireless communications is omnipresent. The range of RF applications is growing rapidly with everything from wearables to smart home appliances requiring reliable, wireless connectivity. ...
