Peregrine Semiconductor Expands UltraCMOS(TM)Digital Step Attenuator Line

7-bit DSA family features unique serial-addressable control
interface
SAN DIEGO--(Business Wire)--
Peregrine Semiconductor Corporation, a leading supplier of
high-performance RF CMOS and mixed-signal communications ICs, today
released three new 7-bit UltraCMOS(TM)

Digital Step Attenuators to complement its popular 50-Ohm DSA
line. Building on their high-performance predecessors, along with
flexible Serial and Parallel interface logic these new
HaRP(TM)-enhanced devices also offer an unprecedented
serial-addressable control interface which allows the user to control
up to 8 different DSAs using a common 3-wire interface bus. The new
trio offers highly flexible attenuation options by covering a 31.75 dB
attenuation range in 0.25 dB, 0.5 dB, or 1.0 dB steps.

The PE43701, PE42702 and PE43703 DSAs offer best-in-class
linearity with and Input IP3 of +57 dBm, outstanding attenuation
accuracy of +/- 0.20 + 2% of attenuation setting at 3 GHz, and low
Insertion Loss of 1.6 dB (typical). As with all UltraCMOS
silicon-on-sapphire RFICs, there is no gate lag to settling time nor
phase shift, making them ideal for next-generation communication
systems such as cellular base stations, repeaters, femtocells and
power amplifier distortion cancelling loops. In particular, the
PE43703 DSA delivers unprecedented settling time making it ideal for
test and measurement applications and a perfect complement to
Peregrine's recently introduced PE42552 RF Switch.

These new 50-Ohm DSAs have an operating frequency range of near DC
up to 6 GHz, with exceptional low-frequency performance, superior
noise immunity and outstanding ESD tolerance of 2.0 kV HBM. They work
with two typical supply voltages of 3.3V or 5V with very low power
consumption, allowing the use of a single devices in both the RF and
IF radio sections to save board space.

Peregrine's PE4370x DSAs provide many additional features,
including on-board CMOS logic which facilitates 2.75 V control, and a
high-alpha state at power-up (PUP). The devices are available in the
following ultra-compact, RoHS-compliant QFN packages: 32-lead 5x5x0.85
mm (PE43701 and PE43703) and 24-lead 4x4x0.85 mm (PE43702). All
products are sampling now and are priced at PE42701: $3.65 (100K
units); PE42702: $3.36 (100K units); and PE42703: $8.20 (100K units).

About UltraCMOS(TM) Technology and the HaRP Technology Innovation

UltraCMOS(TM) mixed-signal process technology is a patented
variation of silicon-on-insulator (SOI) technology on a sapphire
substrate providing with high yields and competitive costs. This
technology delivers significant performance advantages over competing
processes such as GaAs, SiGe BiCMOS and bulk silicon CMOS in
applications where RF performance, low power and high levels of
integration are paramount. The Company's revolutionary HaRP(TM)
technology further exploits the fundamental benefits of
silicon-on-sapphire, enabling dramatic improvements in harmonic
results, linearity and overall RF performance which today remain
unmatched by any other RF process technology.
