Integrating RFID and Sensor Technologies to Advance Systems: Part 2
Design How-To 6/17/2008 Post a comment
Creating an intelligent, converged system is much easier and more affordable than one might think. The first step is to understand the challenges in advancing convergence initiatives, and the limitations of the current business practices. Patrick Esposito II, president and COO at Augusta Systems, tells us how in Part 2 of this two-part series.
GPS RF antenna modules for mobile handset applications
Design How-To 6/16/2008 Post a comment
The most suitable antenna for a fixed receiver provides a beam extending down to about 15deg above the horizon over a range of 360deg azimuth with some gain reduction overhead. However the situation for mobile handsets is not so clear, and in this article we discuss what the best mobile GPS antenna design strategy should be.

Reflections from IMS: Tornadoes
RF & Microwave Designline Blog 6/16/2008 Post a comment
I just attended a panel discussion here at the RFIC Symposium. The topic was "Millimeterwave ICs: Is Silicon Winning? Is GaAs still alive?" After the panel presented, an observation from the floor set off some tornado warnings in my head for RF.
Endgame: Will WiMax and LTE find happiness in multimode?
Design How-To 6/16/2008 4 comments
LTE and WiMax may be two peas in an OFDM pod, but they are not twins. Harmonizing the contenders in orthogonal frequency-division multiplex standards before silicon would have distinct advantages, not the least of which is power consumption.
