Interview: Dr. James Truchard, Microwaves & RF Living Legend Jul 14, 2015 The founder of National Instruments looks back on his long and storied career. IMS 2013 Wrap-Up: Sizing Up The Show Jun 10, 2013 Communications Editor Lou Frenzel offers his final thoughts on IMS 2013. IMS 2013 (Final Countdown): Sleepless In Seattle May 31, 2013 Communications Editor Lou Frenzel reports on the action from IMS 2013. IMS 2012, Day 3: A Sea of Semiconductor Vendors Jun 20, 2012 Think plumbing when you think of microwaves. At least that is the way it used to be. Lots of waveguides and metal structures with cavities. And tubes. Today much of that plumbing is still around for some applications... IMS 2012, Day 2: Closing the Microwave Gap Jun 19, 2012 ... IMS 2012, Day One: 60 Years of Microwaves Jun 18, 2012 ... Oscillator Cuts Phase Noise To -145 dBc/Hz At 10 kHz Sep 20, 2009 This unique and compact oscillator uses optical techniques to generate extremely stable microwave frequencies with low harmonics and low phase noise. Synthesizer Merges Fast Switching With Low Phase Noise Aug 25, 2009 With an ultra-low-noise PLL mechanism called phase refining, this synthesizer brings output phase noise to almost ideally multiplied crystal reference behavior.
