STW81101 Multi-band RF frequency synthesizer with integrated VCOs

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.
