IMS 2012, Day 3: A Sea of Semiconductor Vendors 1
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. Now it is less plumbing and more ...
IMS 2012, Day 2: Closing the Microwave Gap
Day two of the IMS conference in Montreal started off well with a great briefing with Ke Wu, the General Chairman of the conference. He is the guy that led his crew of 65+ individuals and IEEE support staff to put together this massive show. An ...
IMS 2012, Day One: 60 Years of Microwaves
Most wireless today is microwave. But it wasn't always that way. Microwave was initially associated with radar, transmission lines and other special wireless applications like satellites and relay. Now it is a microwave world celebrated this year in ...
Oscillator Cuts Phase Noise To -145 dBc/Hz At 10 kHz
This unique and compact oscillator uses optical techniques to generate extremely stable microwave frequencies with low harmonics and low phase noise.
