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 communications and industrial product line. “Discrete
solutions utilizing pin diodes and mechanical relays simply cannot
support the required linearity from UHF/VHF through LTE operation
while still meeting the size, cost and performance expectations of
high-power wireless systems. Our monolithic approach offers a
reliable solution to these challenges and provide customers with a
route to future proofing their designs as they move to accommodate
additional frequency bands.”
In addition to high linearity (82dBm IIP3 @ 850MHz; 76dBm IIP3 @
2.7GHz), the PE42820 and PE42821 switching ICs feature low
insertion loss (0.35 from 30MHz-1GHz; 0.20 from 1-2GHz; and 0.80
from 2-2.7GHz), and exceptional ESD of 1.5 kV HBM on all pins. The
PE42820/1 high-power switches operate with a wide supply range of
2.3V to 5.5V. The PE42821 is a feature and pin-compatible version
of the PE42820 with a faster switching time of 6μs.
Development Tool SupportPeregrine Semiconductor also
announced availability of the PE42820/1 Evaluation Kits, available
now through Peregrine’s global direct sales representatives and
worldwide distribution partners.
Packaging, Pricing & AvailabilityThe PE42820/821
switches are supplied in RoHS compliant, 5 x 5 mm 32-lead QFN
packages. Pricing for both devices starts at $11.69 in 10k unit
quantifies. Samples and volume-production quantities are available
today by contacting Peregrine. For more information, visit
