Measuring single-tone desensitization for CDMA receivers
May 1, 2005
By Jinku Kim and Dave Devries This article sheds light on two important contributors to single-tone desensitization in CDMA receivers; namely reciprocal mixing and cross-modulation. It also presents a practical low-cost method for measuring single-tone desensitization performance in a CDMA receiver....
The need for advanced silicon modeling in RF nanometer designs
May 1, 2005
By Karen Chow Nanometer technologies, while enabling functionality on a chip, bring a host of additional physical effects for the designer to consider. This is particularly the case with the latest standards in design, such as GSM/GPS/Bluetooth. The physical effects, in addition to re-spin costs in the million-dollar range, make verification indispensable to the mixed-signal generator....
