RF system solution suits Samsung
A quad-band Edge RF system solution from Renesas Technology is being used by Samsung Electronics in its new Edge mobile handset
The RF system was selected by Samsung because it greatly simplifies the implementation of the radio. It has been successfully integrated with Agere Systems' Sceptre HPE2 baseband solution for Edge. The new Edge handset is already in volume production. The highly integrated RF system solution, which is being demonstrated by Renesas Technology at 3GSM Congress in France, was the first full type approval compliant advanced Edge RF system.
