Peregrine Semiconductor Lobs New Patent Suit Against RFMD

San Diego-based RF semiconductor maker Peregrine Semiconductor announced Tuesday afternoon that it has filed a new, patent lawsuit against RF Micro Devices, alleging infringement on its patents. Peregrine Semiconductor said it filed the suite in the U.S. District Court for the Southern District of California. Peregrine already has a patent suit filed against RFMD, which it filed in February of last year. Peregrine said the new patent lawsuit covers U.S. Patent 8,405,147, which it says covers technology that improves the linearity and circuit performance of RF SOI devices.
