Using Single-ended S-matrices to Characterize Differential Components in Mobile Radio Design
Apr 1, 2003
By SangJin Lee In the past, individual RF or IF components tended to be based on differential topology. Widespread use is common within the wireless industry because this topology offers inherent noise immunity benefits. Although these balanced components provide good noise immunity, their structure gives RF designers headaches when characterizing and matching.
A method to accurately measure and characterize such circuits is desirable. The method described here provides a compact way to characterize the...

Securing Unlicensed WLAN Data Communications
Feb 1, 2003
By Bob Cromwell Wireless networking has serious security problems. RF signals sometimes propagate through structures and out of windows, and RF engineers need to understand the major issues of wireless network security, including data integrity and confidentiality, and device authentication. There is technology available today to secure wireless local area networks, and this article will make sense of the alphabet soup of wireless LAN modes, and it will explain security mechanisms and security protocols....
