 ICs enable smaller main and diversity antennas with improved RF performance

SAN DIEGO -- February 25, 2013

Peregrine Semiconductor Corporation (NASDAQ: PSMI), a fabless provider of
high-performance radio frequency integrated circuits (RFICs), today announced
from Mobile World Congress in Barcelona it has expanded its DuNE™ Digitally
Tunable Capacitor (DTC) product line with six second-generation devices for
antenna tuning in 4G LTE smartphones. The PE623060, PE623070, PE623080, and
PE623090 (PE6230x0) DTCs have a capacitance range of 0.6 – 7.7 pF and support
main antenna power handling of up to +34 dBm. The PE621010 and PE621020
(PE6210x0) DTCs have a capacitance range of 1.38 to 14.0 pF and are optimized
for power handling of up to +26 dBm, making them well suited for diversity
antennas. All of the new DTCs are manufactured on Peregrine’s UltraCMOS^®
technology process, with HaRP™ technology enhancements that enable the devices
to meet the challenging harmonic and linearity requirements of LTE. The
highly-versatile devices support a wide variety of tuning circuit topologies,
with an emphasis on impedance matching and aperture-tuning applications. They
extend Peregrine’s high-performance tuning roadmap, which was first introduced
to the market in 2008.

“Smartphones are now required to support a subset of the more than 40
different LTE frequency bands, as well as MIMO and carrier aggregation,” said
Dylan Kelly, vice president of Peregrine Semiconductor’s Mobile Wireless
Solutions business unit. “To keep up, these devices now contain multiple
antennas, making it difficult to keep the end device thin and slim. Tuning the
antenna solution with DuNE DTCs enables the system to support multiple bands,
while at the same time reducing antenna size and providing optimal RF
performance.”

The PE6230x0 and PE6210x0 product families enable designers to develop
smaller, higher-performing antennas. Antenna tuning functions, including bias
generation, integrated RF filtering and bypassing, control interface, and ESD
protection of 2 kV HBM, are incorporated into a slim, 2 mm x 2 mm x 0.55 mm
package. All decoding and biasing are integrated on-chip, and no external
bypassing or filtering components are required. The devices offer superior
tuning accuracy, quality factor, linear step size, and tuning ratio, combined
with excellent power handling and temperature stability. They are controlled
through the widely-supported 3-wire (SPI-compatible) interface and are easy to
incorporate into the RF Front-End design. The DTCs provide a
monolithically-integrated antenna-tuning solution that improves Total Radiated
Power (TRP), with direct battery voltage operation, enabling a more efficient
smartphone with extended battery life.

PE6230x0 Product Family Features

The PE6230x0 DTCs are optimized for key cellular frequency bands from 700 to
2,700 MHz, featuring direct battery voltage operation with consistent
performance enabled by on-chip voltage regulation. They have IIP3 of >+70 dBm
at 50 Ohm and exceptional harmonic performance of 2fo/3fo = -40/-50 dBm @ 34
dBm RF (900 MHz) and 32 dBm RF (1900 MHz). The 5-bit, 32-state PE623060/70/80
DTCs have a capacitance range of 0.9 to 4.6 pF (5.1:1 tuning ratio) in
discrete 119 fF steps; 0.85 to 2.4 pF (2.82:1 tuning ratio) in discrete 50 fF
steps; and 2.15 – 7.7 pF (3.6:1 tuning ratio) in discrete 180 fF steps,
respectively. The 4-bit, 16-state PE623090 DTC has a capacitance range of 0.6
to 2.35 pF (3.9:1 tuning ratio) in discrete 117 fF steps. The lower minimum
capacitance of the PE623090 DTC solves a critical problem in high-frequency
tuning.

PE6210x0 Product Family Features

The 5-bit, 32-state PE6210x0 DTCs support the 100 to 3,000 MHz frequency
range. These DTCs extend the range of diversity antennas and improve data
rates by optimizing the antenna performance at the operating frequency. The
PE621010 DTC has a capacitance range of 1.38 – 5.90 pF (4.3:1 tuning ratio) in
discrete 146 fF steps; the PE621020 of 1.88 – 14.0 pF (7.4:1 tuning ratio) in
discrete 391 fF steps.

Development Tool Support

Peregrine also announced the PE6230x0 and PE6210x0 Evaluation Kits today, to
help designers get started using the new DTCs in their applications. The kits
include an interface board and USB cable to enable quick evaluation,
prototyping, and debugging via simple-to-use Graphical User Interface
(GUI)-based control software. They can be ordered today, through Peregrine’s
global direct sales management. For more information, visit

Packaging & Availability

The PE6230x0 and PE6210x0 DTCs are available in a 10- and 12-lead, 2 mm x 2 mm
QFN packages, respectively. Samples and volume-production quantities can be
ordered today, through Peregrine’s global direct sales management. For more
