Showing high performance, high integration, low power, and multi-band performances, STW81102 is a low cost one chip alternative to discrete PLL and VCOs solutions. STW81102 includes an Integer-N frequency synthesizer and two fully integrated VCOs featuring low phase noise performance and a noise floor of -155d Bc/Hz. The bination of wide frequency range VCOs (thanks to centerfrequency calibration over 32 sub-bands) and multiple output options (direct output, divided by 2 or divided by 4) allows to cover from 750MHz to 905MHz and 1000MHz to 1162.5MHz, from 1500MHz to 1810MHz and 2000MHz to 2325MHz, from 3000MHz to 3620MHz and...
