2.6 GHz/800 MHz Dual Fractional-N/Integer-N Frequency Synthesizer

The SKY74038-21 provides RF/main and IF/auxiliary synthesizers that operate at up to 2.6 GHz and 800 MHz, respectively. The device meets the fast settling time requirements for compressed mode of operation, while also meeting the low power consumption requirements of terminal applications. The ultra-fine frequency step size (down to 10 Hz) makes the SKY74038-21 adaptable for multimode/multiband operation. Additionally, the ultra-fine frequency step size can be used for frequency drift compensation. The SKY74038-21 is ideal for GSM/3G/paging base stations, mobile radios, telematics, and many other applications.
