LOL! RFMD does 3g transmit modules as well and also does power modules/amplifieres for 4g base. 2G is for emerging markets, gosh, must be a big market to move from 25 million in Dec to over 100 million this month. What was that....oh, 3 months! rfmd also does power amplifiers for samsung 3g. RFMD seems to have its hands in on many componets inside a cell phone but their claim to fame as i understand it is the reduced size, reliability, and extended life of its power amplifiers. this give OEMs more board space so to speak, regarding what apps go into its smart phone etc.
They might have 3G and 4G amplifiers in their catalog but in reality they are not getting the big design wins here. Their legacy 2G products are still carrying them. In order to stay in the game they will need to start winning more market in 3G and 4G. They are being forced to play catch up for these markets.
Their cell phone chips may be ancient, but I heard they're working on a solar-powered phone with a built-in LED flashlight. Nobody else has a solar-powered phone, let alone a phone-flashlight combo unit. Very cool.
