  Peregrine Semiconductor Files Additional Patent Infringement Action Against
  RF Micro Devices

Business Wire

SAN DIEGO -- March 26, 2013

Peregrine Semiconductor Corporation (Peregrine Semiconductor) (NASDAQ: PSMI),
a leading provider of high-performance radio frequency integrated circuits
(RFICs), today announced that it has filed a new lawsuit in U.S. District
Court alleging the infringement of Peregrine patented intellectual property
relating to RFICs and switching technology by RF Micro Devices, Inc. (RFMD).

The suit filed in U.S. District Court for the Southern District of California
claims that certain RFMD products infringe a newly issued Peregrine patent
relating to silicon-on-insulator (SOI) technology for RFICs. Peregrine seeks,
in addition to damages, to permanently enjoin RFMD from further infringement.
This new legal action is in addition to an existing lawsuit filed against RFMD
in February 2012 and currently pending in U.S. District Court.

The new patent, U.S. Patent 8,405,147, concerns Peregrine’s HaRP™ invention
that significantly improves the linearity and circuit performance of RF SOI
devices. Peregrine believes the HaRP™ invention is instrumental for RF SOI
devices to successfully meet the demanding RF requirements of advanced mobile
wireless applications such as 4G LTE.

“Peregrine has enabled significant advancement in the RF front-end
architectures of mobile wireless devices with our high-performance products
and technology. Our innovative products are used extensively in the latest
generation of mobile devices,” said Jim Cable, president and chief executive
officer. “Peregrine’s proprietary UltraCMOS^® process and design technologies
are the result of more than 20 years of intensive research and development
activity and the investment of approximately two hundred million dollars.
Peregrine is committed to a vigorous defense of its intellectual property and
continuing advancements in the field.”

Peregrine has been awarded numerous U.S. and foreign patents based on its
pioneering work in developing and manufacturing high-performance products
using CMOS-based semiconductor manufacturing processes. These patented
innovations allow RFICs to deliver a unique combination of high levels of
monolithic integration and performance, small size and low power consumption.
