MTT-S 2007: Skyworks Launches High-Dynamic-Range Direct Demodulators For Wireless Applications

Honolulu -- IEEE MTT-S International Microwave Symposium -- Skyworks Solutions, Inc. unveiled the first of several forthcoming direct demodulators for use in various wireless communication applications, including WiMAX and cellular infrastructure. The SKY73012, which is suitable for quadrature demodulation of RF waveforms from 400 to 3900 MHz, allows customers to integrate a single solution across an entire spectrum of radios rather than requiring multiple demodulators for various frequency ranges.

"By eliminating intermediate frequency stages of the receiver, our solution offers cellular infrastructure designers an unprecedented degree of design flexibility," said Sean Martin, senior director of Linear Products at Skyworks. "At the same time, given Skyworks' ability to deliver high levels of analog integration, we are able to significantly reduce costs for high performance receivers with demanding linearity requirements. Our demodulator is yet another example of our success with leveraging our core analog and RF strengths across a wide range of applications to serve new markets and meet customer needs."

The SKY73012 is an integrated, broadband, high-dynamic range quadrature demodulator with outputs that are differential and can be directly connected to most commonly available analog to digital (A/D) converters. It is also a suitable solution for CDMA, UMTS, GSM/GPRS receivers, WiMAX (IEEE 802.16) radios, RFID readers, power amplifier (PA) feedback/linearization, wireless local loops (WLLs), and wireless local area networks (WLANs).

The high dynamic range and second order input intercept point (IIP2) and IIP3 value of the SKY73012 make it suited for use in direct conversion and low intermediate frequency (IF) receivers. The device features integrated LO balun and amplifier, differential IF output, on-chip in-phase and quadrature (I/Q) phase splitter, and a single +3.0 volt (V) supply. The SKY73012 is also manufactured in lead (Pb)-free, restriction of hazardous substances (RoHS)-compliant packaging.

The SKY73012 is currently available and in volume production.
