The synthesizer provides a complete CMOS RF synthesizer in a single low-profile, small-outline 24-pin package. It integrates three voltage-controlled oscillators (VCOs), loop filters, reference and VCO dividers and phase detectors, reducing board space requirements by 75 percent. It also features a proprietary self-tuning architecture that does not require VCO modules and provides the ability to achieve the fast settling times required for GPRS. The unit performs RF synthesis in two bands, 900 MHz to 1.8 GHz and 750 MHz to 1.5 GHz, as well as IF synthesis from 62.5 MHz to 1.0 GHz.
