Two trends are well underway in portable and handheld consumer electronic devices: shrinking form factors and the integration of multiple wireless technologies, such as Bluetooth™, cellular, GPS and Wi-Fi. These trends create challenges for device vendors and integrators by increasing the likelihood of RF noise and other system interactions that can undermine antenna performance.

This paper looks at the evolution of the mobile backhaul network and the very network that will eventually carry the increasing broadband traffic.

RF susceptibility or immunity test systems are often configured as dynamic hardware solutions that address more than one of the ever changing EMC standards. Automation by way of a software driven RF test system controller provides signal routing switch matrices and improves test reliability and engineering productivity.

Printed circuit boards with both analog and digital circuitry are nearly universal. Recently, integration of RF circuitry in addition to the mixed analog and digital circuits has become more common. Problems arise because the PCB design tools have been ignorant of RF shapes printed on the board and a great deal of manual work was required to achieve a functioning product. Mentor has teamed with RF Design Tool suppliers, such as Agilent, to bring to market the first integrated RF-PCB system tool.

Since crosstalk jitter is uncorrelated from the link data pattern, it is hard to remove through equalization techniques. This paper provides a process to extract accurate coupled models from connectors. It also describes how modeling was used to predict crosstalk noise in a 10Gbps channel.

This paper presents multiple architecture options available to fill different design needs,Single mode architectures optimized for performance and converged multi-mode architectures optimized for size and solution configuration.

This paper will help you to ask the relevant questions when choosing from the many analyzers available in the market today. It will help you make a well-informed decision when purchasing an instrument to measure and display frequency vs. amplitude.

This paper will describe OFDM and show why it has the ability to improve the spectral efficiency of digital radio links. It will also discuss the use of Multiple Input/Multiple Output (MIMO) antennas to improve signal reception and combat the effects of multipath fading.

This article describes a technique based on envelope tracking that has been proven to offer a dramatic improvement in efficiency, from typically 15% to over 50%, while offering multiband performance.

This paper focuses on challenges wireless companies and their transmission engineers are facing in order to meet the capacity, reliability, performance, speed of deployment, and cost challenges in microwave point-to-point networks.
