Peregrine Enables New Approach to RF Switching in High-Power
Wireless Systems
UltraCMOS® technology delivers unprecedented combination of 30W power handling
and excellent linearity across the UHF/VHF through LTE frequency bands
San Diego, California, September 11, 2013
-- Peregrine Semiconductor Corporation (NASDAQ: PSMI),
a fabless provider of high-performance radio frequency integrated circuits (RFICs), today announced the
PE42820 and PE42821 single-pole double throw (SPDT) switches for high-power wireless applications.
The new switches provide an unprecedented combination of high-power handling and excellent linearity
while offering an integrated approach that reduces board area, power consumption and design-in
complexity compared to traditional discrete solutions. This combination makes the PE42820/821 ideal for
transmit/receive, filter bank and antenna band switching applications in high-power RF systems such as
wireless infrastructure devices and land mobile radios for public safety and military environments.
Peregrine’s new switching ICs are significant in replacing discrete solutions including traditional
pin diodes used in land mobile radios (LMR), and mechanical relays used in LTE-enabled small cells or
distributed antenna systems. These discrete solutions cannot deliver both the high power handling and
high linearity required for broadband frequency support as required for LMR and LTE convergence. In
contrast, the PE42820/821 switching ICs offer high 30W power handling while also enabling excellent
linearity across the entire 30MHz to 2.7GHz frequency range. This combination, enabled by Peregrine’s
UltraCMOS® technology with HaRP™ enhancements, improves signal clarity and range in high-power
RF systems.
In addition, Peregrine’s monolithic
approach integrates flexible control voltage
ranges, which eliminates the need for external
bias control circuitry. This reduces the system
bill of materials, thereby saving on board space
and current consumption, while simplifying
design for a more reliable long-term solution.
“The increased complexity that comes
from supporting additional frequency bands in
high-power wireless applications necessitates
a new approach to system design,” said Mark
Schrepferman, director of Peregrine’s
