‘Cellphone’

An Electronicstalk guide

Start with the news release Power Integrations extends Linkswitch-II family from Power Integrations, which we summarised at the time by saying "Power Integrations has expanded its Linkswitch-II product family with the introduction of the LNK632DG. ". Several months prior to that, we featured the news release Voice processor clears up Korean calls from Audience: "The LG Electronics LG-SH400 mobile phone launched by SK Telecom last week features the Audience Voice Processor.".
 
In July 2008, we covered the news from Cambridge Silicon Radio - take a look at Bluetooth demo proves low-energy technology which says: "Demonstration features two Bluetooth low energy devices transferring data to a handset using a Bluetooth low energy advertising packet with no prior configuration or pairing.".
 
Take a look also at the news release from Analog Devices, RF detectors are ready for cellular evolution, as well as Slimline LED sheds light for autofocus from Avago Technologies, and Processor provides link from handset to TV from NXP Semiconductors.
