Peregrine Enables New Approach to RF Switching in High-Power Wireless Systems



  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 -- 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 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 Support
Peregrine 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 & Availability
The 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.
