Multi-band RF Frequency Synthesizer With Integrated VCOs

The STMicroelectronics STW81103 is an integrated RF synthesizer with voltage controlled Oscillators (VCOs). Showing high performance, high integration, low power, and multi-band performances, STW81103 is a low cost one chip alternative to Discrete PLL and VCOs solutions. STW81103 includes an Integer-N frequency synthesizer and two fully integrated VCOs featuring low phase noise performance and a noise floor of -155dBc/Hz. The combination of wide frequency range VCOs (thanks to center- frequency calibration over 32 sub-bands) and multiple output options (direct output, divided by 2 or divided by 4) allows to cover the 625MHz- 762.5MHz, the 1087.5MHz-1525MHz, the 2175MHz-3050MHz and the 4350MHz-5000MHz bands. The STW81103 is designed with STMicroelectronics advanced 0.35m SiGe process. By STMicroelectronics
