PCB design considerations for wireless Data Logger used for thermal validation system

Printed circuit board layout becomes more complex because of the increased devices pin density and system frequency, respectively. A successful high-speed board must effectively integrate devices and other elements while avoiding signal transmission problems associated with high-speed I/O standards. This paper provides guidelines for effective 2.4GHz wireless Data Logger used to measured temperature, regarding the following issues: PCB material selection, transmission line layouts, routing schemes for minimizing crosstalk and maintaining signal integrity, and electromagnetic interference. The Data Logger temperature range is from -60°C to 150°C with accuracy of 0.1°C for each measurement.
