Description

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 -155dBc/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

825MHz-1100MHz, 1650MHz-2200MHz and

3300MHz-4400MHz bands.

The STW81101 is designed with

STMicroelectronics advanced 0.35µm SiGe

process.
