Despite chipmaker Infineon’s recent warning, Nokia said its plan for single chip handsets is still on track. The German chipmaker announced that its project to provide Nokia with chips that include multiple radios on a single chip has been delayed.

Nokia said that the single-chip solution is “progressing according to plan,” and that with multiple suppliers it doesn’t expect to feel the impact from Infineon’s announcement. Nokia is also working with Texas Instruments, Broadcom and STMicroelectronics.

Along with its announced delays, Infineon also said that it has received lower than expected orders to supply HSDPA chips for high-speed handsets. The chipmaker did not reveal which handset maker the 3G chipsets were for. Matt Thornton, telecommunications analyst at Avian Securities, wrote in a research note that Infineon’s negative announcement “could imply a slower launch for Apple’s 3G iPhone or slowness in Samsung’s 3G devices.”

Earlier this week, the chipmaker’s CEO said he would step down over differences regarding the company’s strategy.
