The STMicroelectronics STW81101 is an integrated RF synthesizer with voltage controlled oscillators (VCOs). Showing high performance, high integration, low power, and multi-band performances, STW81101 is a low cost one chip alternative to discrete PLL and VCOs solutions. STW81101 includes an Integer-N frequency synthesizer and two fully integrated VCOs featuring low phase noise performance and a noise floor of -154dBc/Hz. The combination 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 the 825MHz1100MHz, the 1650MHz-2200MHz and the 3300MHz-4400MHz bands. |
