IDT Expands Industry-leading RF Signal Chain Portfolio With High-performance DPD Demodulator for Wireless Base Stations
SAN JOSE, Calif. --(Business Wire)--
Integrated Device Technology (News - Alert), Inc. (IDT®)
(NASDAQ:IDTI), the Analog and Digital Company™ delivering essential
mixed-signal semiconductor solutions, today announced the expansion of
its industry-leading RF
signal chain portfolio with a high-performance digital
pre-distortion (DPD) demodulator. The new integrated DPD
demodulator improves system performance while reducing solution
cost, physical size and power consumption in 4G, 3G, and 2G wireless
base stations and repeaters.
are high-performance, low-power DPD demodulators optimized for 400 MHz
to 1200 MHz and 1300 MHz to 2900 MHz wireless systems, respectively. The
fully-integrated solutions include a demodulator, digital
step attenuator (DSA),
and high-isolation single-pole double-throw (SP2T) switch to minimize
system solution cost, board footprint, and bill-of-materials. The
devices' innovative architecture and design, coupled with a high level
of integration, offer over one Watt of power savings compared to
conventional solutions. This results in reduced heat dissipation and
energy usage, helping to ease cooling requirements, promote smaller
equipment form factors, and lower operating costs. In addition, the new
DPD ICs offer excellent linearity and high bandwidth, making them an
ideal, flexible solution for linearizing any type of BTS transmitter.
"IDT's new DPD demodulator offers customers tremendous benefits in
performance and integration," said Christian
Kermarrec, vice president and general manager atIDT. "Innovative
design techniques have allowed us to integrate important functions into
a single chip, producing a highly-compact, low-power solution with
exceptional linearity and high bandwidth. This enables our customers to
reduce solution cost, simplify the PCB, and minimize heat dissipation -
critical factors in next-generation wireless base station equipment
designs. These devices complement our rich portfolio of radio card
products, including RF
gain amplifiers, digital
step attenuators, data
converters, and high-performance
The new DPDs include a high-isolation SP2T switch, allowing for easy
integration into multiple input, multiple output (MIMO) systems, while
the integrated Glitch-Free™ DSA enables dynamic adjustment to optimize
the power of the incident signal reaching the demodulator. Furthermore,
the Zero-Distortion™ demodulator is able to drive the analog-to-digital
directly, eliminating the need for intermediate frequency variable
gain amplifiers (IF VGAs) in most applications.
In addition, the extremely high dynamic range of the IDTF1320 and
IDTF1370 results in enhanced DPD loop performance, minimizing the
adjacent channel leakage-power ratio (ACLR) and error vector magnitude
(EVM). This promotes better system-wide transmitter performance and
enables wireless service providers to deliver higher-bandwidth internet
and data services over existing frequency bands - a key challenge in
today's heavily-utilized wireless communication infrastructure.
