Did This Supplier Reveal the iPhone 5S Launch Date?

Will Apple’s (NASDAQ:AAPL) iPhone 5S debut in September? Avago Technologies (NASDAQ:AVGO), an Apple supplier that makes chips for the iPhone, is reporting various preparations for increased production of a new product from its biggest North American customer.

Via Apple Insider, Wells Fargo analyst Maynard Um writes in a note to investors that these “signs of life” in Apple’s supply chain are a good indication that the company will be releasing its iPhone 5S in September. If the iPhone 5S launches on September 12, it would debut exactly one year from the launch of the iPhone 5.

“Avago noted it is already seeing an initial ramp of a new product transition (we believe iPhone 5S) and expects a greater ramp in the following quarter (October quarter),” writes Um. Um has earlier stated that Apple is also likely to use AuthenTec’s fingerprint sensor technology in the iPhone 5S, either as a way to unlock the phone or a method of processing payments.

Apple acquired AuthenTec last summer and seemed to be primarily interested in the company’s patent for a fingerprint sensor technology. KGI Securities analyst Ming-Chi Kuo has also claimed that the next iteration of iPhone will feature a fingerprint sensor.
