SAN DIEGO -- September 24, 2013

Peregrine Semiconductor Corporation (NASDAQ: PSMI), a fabless provider of
high-performance radio frequency integrated circuits (RFICs), today announced
the highest performance, carrier-grade Wi-Fi switch on the market. With the
highest isolation by a factor of 50, Peregrine’s switch also sets a new bar in
linearity, which makes it ideally suited for the fast-growing market of
802.11ac Wi-Fi access points.

“Mobile Experts’ research shows the number of carrier-grade Wi-Fi access
points deployed has grown 40 percent this year alone," said Joe Madden,
founder and principal analyst at Mobile Experts. "With the Wi-Fi market shift
to dual-band 802.11ac support, we predict the market for RF suppliers – such
as Peregrine – will grow even faster at a rate of 50 percent annually through

The rising amount of cellular-data offload to Wi-Fi networks is significantly
increasing the complexity of access-point radios. Most Wi-Fi access points now
contain multiple radios in order to address the capacity demands of cellular
data. Based on Peregrine’s UltraCMOS^® technology, the PE42423 is the first in
its class to offer 41 dB of port-to-port isolation at 6 GHz. This
best-in-class isolation enables multi-radio access points to perform at peak
levels without interference between the radios. Exceeding the stringent
802.11ac standard, Peregrine’s switch also offers 65 dBm of linearity to
achieve higher data rates. In addition, UltraCMOS technology delivers equally
high performance at either 3.3V or 5V, unlike gallium arsenide (GaAs) switches
that experience severe performance degradation below 5V. Peregrine’s switch
gives networking-product designers the flexibility to operate at lower power
supplies and reduce energy consumption.

“Peregrine’s long-standing leadership in RF switches, combined with our
UltraCMOS technology, has enabled us to develop the highest performance,
carrier-grade Wi-Fi switch on the market,” said Dave Shepard, vice president
of Peregrine’s high-performance solutions business unit. “Peregrine is
committed to meeting the Wi-Fi data-rate and capacity demands of the future,
and we are already helping networking vendors achieve unprecedented
performance using this switch in their Gigabit Wi-Fi access points.”

Features, Packaging, Pricing & Availability

Now shipping, Peregrine’s PE42423 is a Single-Pole Double Throw (SPDT) RF
switch featuring low insertion loss (0.8 dB @ 2.4 GHz, 0.95 dB @ 5.8 GHz),
fast switching time (500 ns) and high ESD ratings (3.0 kV HBM on all RF pins).
The switch supports +1.8V standard logic control. It provides stable RF
performance over a power supply range between 2.3V and 5.5V. The packaging is
RoHS compliant, 16-lead QFN and measures 3 x 3 mm. View the PE42423 press kit
