RF Micro Devices (RFMD) is climbing after Lazard analyst Ian Ing upgraded the stock to Buy from Neutral in a note to investors earlier today. RF Micro slumped yesterday after Qualcomm (QCOM) announced that it would introduce a cellular radio frequency band fragmentation device called the Qualcomm RF360 Front End Solution. RF Micro markets similar products. Ing, however, wrote that fears about the effects of Qualcomm's new product on RF Micro are likely overdone. Qualcomm's front end product is largely a "proof of concept" solution meant to push other companies to solve band fragmentation issues, rather than a product that could become dominant and threaten RF Micro, the analyst wrote. Qualcomm is unlikely to risk alienating its key partners in the radio frequency space by pursing a product that would increase its operating income by less than 10%, according to the analyst. Ing is upbeat on RF Micro's outlook, and he set a $6 price target on the shares, which climbed 13c, or 3%, to $4.75 in early afternoon trading. Other makers of RF solutions that fell yesterday are also recovering today. Skyworks (SWKS) advanced 3.5% to $22, and Avago (AVGO) added 1.5% to $34.20.
