Keeping Solder in Place With Laser Ablation

January 17, 2012
To prevent unwanted flow, many PCB designers will install dams formed of glass or other dielectric materials to keep solder from shorting active areas on a circuit. But there is another solder damming technique being rapidly adopted—laser ablation. Considered to be more accurate and consistent than traditional solder damming methods.

Introduction to MIMO

January 17, 2012
Modern radio communication systems have to provide higher and higher data rates. As conventional methods like using more bandwidth or higher order modulation types are limited, new methods of using the transmission channel have to be used. Multiple antenna systems (Multiple Input, Multiple Output – MIMO) gives a significant enhancement to data rate and channel capacity. This application note gives an introduction to basic MIMO concepts and terminology and explains how MIMO is implemented in different radio communications standards.

HSPA+ Technology Introduction

January 17, 2012
High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) optimize UMTS for packet data services in downlink and uplink, respectively. Together, they are referred to as High Speed Packet Access (HSPA). Within 3GPP release 7 and 8, further improvements to HSPA have been specified in the context of HSPA+ or HSPA evolution. This application note introduces key features of HSPA+ and outlines the changes to the radio interface.
