STW81103 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 0.35µm SiGe process.
