PicoGuard Device offers protection for Antennas in Mobiles

Growing Demand for Multimedia and Wireless Internet Capabilities

“In spite of the current contraction of the handset market, consumers are showing increased demand for handsets featuring advanced multimedia and wireless Internet connectivity. Feature phones and smart phones that incorporate FM receivers, GPS, Bluetooth and WLAN are expected to grow as a category at a 62% CAGR from 2008 through 2011, a rate 22 times faster than handset market growth for this same period,” said Tina Teng, Senior Wireless Communications Analyst for iSuppli Corporation. In addition to the mobile handset market, location based services using GPS are also becoming increasingly popular in today’s latest laptop, PDA and netbook designs. The internal antennas that are required are highly susceptible to ESD strikes that can damage the handset’s internal baseband and application processors.

When selecting ESD protection devices, mobile handset designers need to consider capacitance, standard ESD ratings, and, most importantly, clamping voltage and dynamic resistance. The amount of dynamic resistance determines the amount of residual current and voltage that the device being protected is subjected to during an ESD event. The lower the dynamic resistance of the ESD protection diode, the greater the portion of the current and voltage that is diverted away from the device being protected.

Static Fee Mats are specialists in the protection of electrostatic discharge in the workplace. ESD protection is important to protect components external to mobile devices also. When mobile devices are in production great care needs to be employed to avoid static electricity entering the area. ESD protection mats such as Static Free Mat’s Benchtop Stat Mat are ideal for economically covering large workbenches.
