Highly-Integrated RF Synthesizer Enters GPRS Wireless Mart

A high level of integration coupled with fast settling times are expected to help make the Si4133G dual-band RF synthesizer a key player in the market for General Packet Radio Services (GPRS) wireless datacomm components. By integrating three voltage-controlled oscillators (VCOs), loop filters, reference and VCO dividers, phase detectors, and other circuitry into this CMOS RF synthesizer, the firm claims that board space requirements can be reduced by 75%, costs can be lowered by 33%, and power efficiency and performance dramatically improved compared to existing solutions. And by achieving settling times of
