IDT Low-band RF Mixer Enhances Mobile Experience by Reducing Intermodulation Distortion in Crowded Spectrum for 4G LTE, 3G, and 2G Systems

IDT’s New Zero-Distortion 450MHz/LTE/EGSM BTS Diversity Mixer Covers the Low-band Frequency Range, Simultaneously Offering Improved System IM3 Performance and Reduced Power Consumption

SAN JOSE, Calif., August 8, 2012 – Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced that it has added a low-band RF mixer that enhances the user’s mobile connectivity experience by reducing intermodulation distortion in the crowded frequency spectrum for 4G LTE, 3G, and 2G systems. IDT’s new Zero-Distortion™ base transceiver station (BTS) diversity mixer offers improved system third-order intermodulation distortion (IM3) performance with reduced power consumption, covering the 450 MHz, Long-term Evolution (LTE) and extended global system for mobile communications (EGSM) frequency range.

          The IDT F1102 is a low-power, low-distortion dual 400 - 1000 MHz RF-to-IF mixer that improves IM3 by over 15 dB, while simultaneously reducing power consumption by over 40 percent compared to standard mixers. These performance qualities result in better signal-to-noise ratio (SNR) for improved quality of service (QoS), along with lowered heat dissipation to ease heat-sinking requirements in the densely-populated radio card enclosure (1.15 W at 5 V and up to +43 dBm IP3O). Offering unmatched performance and efficiency, the F1102 is ideal for multi-carrier, multi-mode 4G LTE and EGSM BTS systems.

          “Having observed the superior performance of our high- and mid-band mixers, our customers are demanding this product,” said Tom Sparkman, vice president and general manager of the Communications Division at IDT. “Our Zero-Distortion technology enables the customer to increase the radio card’s front-end gain to improve SNR, while simultaneously reducing distortion in the crowded EGSM and U.S. cellular bands. With our broad portfolio of high-performance, low-power variable gain amplifiers (VGAs), industry-leading timing, serial switching, data conversion and data compression products, IDT is a one-stop shop for communications signal chain solutions.”

          As with other members of IDT’s mixer family, the F1102 offers fast settling time and a constant local oscillator (LO) input impedance in power-up and -down modes. This allows customers to power-down the mixer between time-division duplex (TDD) receiver slots, further reducing power consumption. In addition, the IDTF1102 can be used with either high-side or low-side injection, and is pin-compatible with existing devices on the market, offering a compelling upgrade option.

          The IDT F1102 is currently sampling to qualified customers and is available in a 36-pin 6x6 mm QFN package. For more information about IDT’s RF signal path solutions, visit
