The New, Pin-Compatible UltraCMOS® PE4312 RF
Digital Step Attenuator (DSA) Succeeds Peregrine’s Flagship
PE4302
Peregrine Semiconductor Corp. (NASDAQ: PSMI), founder of RF SOI
(silicon on insulator) and pioneer of advanced RF solutions,
introduces its next-generation, UltraCMOS PE4312 DSA. Successor to
the popular PE4302 – which boasts more than 35 million units
shipped since its introduction – the new PE4312 enables flexible,
wide dynamic-range network-infrastructure designs that require
highly accurate and efficient amplitude control. This DSA upgrade
is ideally suited for wireless-infrastructure devices, broadband
consumer and infrastructure equipment, land mobile radios (LMRs),
test-and-measurement equipment and military RF applications.

step attenuator offers flexibility and performance for wireless-
and broadband-infrastructure equipment, LMRs, test-and-measurement
equipment and military RF applications. (Photo: Business Wire)
“Peregrine created the category of digital step attenuators with
the UltraCMOS PE4302, and today’s announcement of our
next-generation DSA will enable us to preserve our market
leadership as the DSA category demands evolve,” says Kinana
Hussain, senior marketing manager at Peregrine. “Based on customer
requests, the UltraCMOS PE4312 features an extended temperature
range that enable RF engineers to simplify thermal design, wider
power-supply range to enable flexible power-supply routing, 1.8
V-compatible control voltage levels to enable lower-power designs
and higher ESD ratings to ease manufacturing flow.”
UltraCMOS PE4312 Sets New Performance Bar for DSAs
Peregrine’s PE4312 is the only DSA on the market to meet a low
insertion loss of 2.1 dB at 4 GHz at any power-supply level between
2.3 V and 5.5 V. It also handles the industry’s widest temperature
range between -40 and 105 degrees Celsius and supports both 1.8 V
and 3 V control logic. In addition, the PE4312 offers several
improvements over PE4302 in attenuation accuracy ±(0.15 + 2% of
attenuation setting), linearity (IIP3 of 59 dBm) and switching
speed (500 ns). Finally, the PE4312 features a novel architecture
to provide safe attenuation-state-transition behavior, which
prevents positive power spikes that occur during attenuation-state
changes when RF input power is applied. This feature simplifies the
digital-interface design, improves signal quality and prevents
damage to power amplifier sub-assemblies.
DSAs Improve Performance of Devices in Many Markets
Based on increasing RF-performance demands, Peregrine’s DSAs
deliver substantial benefits to wireless-infrastructure devices,
broadband TV modems, LMRs, test-and-measurement equipment and
military RF applications. Peregrine DSAs are in multiband,
RF-infrastructure applications and deliver power control in
distributed antenna systems; gain control for optical repeaters in
wireless-infrastructure devices; signal conditioning in broadband
equipment; and amplitude conditioning in test-and-measurement
equipment and LMRs.
Features, Packaging, Pricing and Availability
Peregrine’s PE4312 is a 50-ohm, 6-bit RF DSA with a 31.5 dB
attenuation range in 0.5 dB steps. It maintains high linearity of
+59 dBm IIP3 and monotonicity from 1 MHz through 4 GHz. Pin-for-pin
compatible with the PE4302, the PE4312 DSA features multiple
programming modes, including serial, direct parallel, and latched
parallel, making it easy to design it into a wide range of systems.
The PE4312 has high, monotonic attenuation performance of 0.5 dB up
to 4 GHz, which improves instrument sensitivity and performance.
Fast switching time of 500 nanoseconds improves system response
times. ESD protection of 1.5 kV HBM eases manufacturing and
prolongs the life of the end product. The 1.8 V and 3 V control
logic support makes it easy to integrate the DSA with the latest
FPGAs. High integration in a single package eliminates the need for
the discrete components and bias circuits that are required with
pin-diode solutions, further easing design and reducing board
space. The PE4312 also features an external negative supply option.
Its packaging is RoHS compliant, 20-lead QFN, and it measures 4 x 4
mm. Samples and volume-production parts are available now and
priced at $1.52 each in 10K-quantity orders. Evaluation kit boards
are $150. For more detail, view the PE4312 press kit for images and
datasheet.
