    產(chǎn)品信息

    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 VCO solutions.

    The STW81101 includes an integer-N frequency synthesizer and two fully integrated VCOs featuring low phase-noise performance and a noise floor of -155 dBc/Hz. The combination of wide frequency range VCOs (using center-frequency calibration over 32 sub-bands) and multiple output options (direct output, divided by 2, or divided by 4) allows coverage of the 825 MHz-1100 MHz, 1650 MHz-2200 MHz and 3300 MHz-4400 MHz bands.

    The STW81101 is designed with STMicroelectronics advanced 0.35 μm SiGe process.

    意法半導(dǎo)體的stw81101是一個集成的射頻合成器和壓控振蕩器(VCO)。呈現(xiàn)出高性能、高集成度、低功耗、多stw81101樂隊的演出,是一種低成本的單芯片替代分立PLL和VCO的解決方案。

    stw81101包括頻率合成器和完全集成的壓控振蕩器具有低相位噪聲性能和噪聲地板- 155 dBc / Hz。寬頻率范圍的壓控振蕩器的組合(使用中心頻率校準(zhǔn)過的32個子帶)和多個輸出選項(直接輸出,除以2,或除以4)允許825 mhz-1100兆赫覆蓋,1650 MHz和3300 MHz頻段mhz-2200 mhz-4400。

    意法半導(dǎo)體的stw81101設(shè)計先進(jìn)的0.35μm SiGe工藝。
