IDT Expands Industry-leading RF Signal Chain Portfolio With High-performance DPD Demodulator for Wireless Base Stations

IDT’s New Integrated Digital Pre-Distortion Demodulator Improves System Performance while Reducing Solution Cost, Physical Size, and Power Consumption in Wireless Base Stations

SAN JOSE, Calif. — (BUSINESS WIRE) — January 21, 2014 — Integrated Device Technology, 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.

The IDTF1320 and IDTF1370 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 at IDT. “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 mixers, variable gain amplifiers, digital step attenuators, data converters, and high-performance timing ICs.”

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 converters ( ADCs) 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.

Product Availability

The IDTF1320 and IDTF1370 are currently available to qualified customers in a compact, 6x6 mm 36-ld VFQFPN package. For more information about IDT’s broad portfolio of RF signal chain products, visit www.idt.com/go/RF.
