Using Calibration to Optimize Performance in Crucial Measurements
Skyworks Solutions Inc., an innovator of high performance analog and mixed signal semiconductors enabling mobile connectivity, unveiled the first of several forthcoming direct demodulators for use in various wireless communication applications, including WiMAX and cellular infrastructure. The SKY73012, which is ideal for quadrature demodulation of RF waveforms from 400 to 3900 MHz, delivers breakthrough simplicity, allowing 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.”
Skyworks launched its Linear Products business to aggressively leverage the company’s core RF and analog product portfolio and modeling capabilities, along with its strong catalog sales channels and specialized rep and distributor networks, in non-handset applications. Thus far, Skyworks has secured several strategic design wins in the infrastructure, broadband, automotive and industrial markets.
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 an ideal solution for CDMA, UMTS, GSM/GPRS receivers, WiMAX (IEEE 802.16) radios, RFID readers, power amplifier (PA) feedback/linearization, wireless local loops (WLL) and wireless local area networks (WLAN).
The high dynamic range and second order input intercept point (IIP2) and IIP3 value of the SKY73012 make it ideal 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 V supply. The SKY73012 is also manufactured in lead (Pb)-free, restriction of hazardous substances (RoHS)-compliant packaging.
