Description

The STMicroelectronics STW81100 is an integrated RF synthesizer and voltage controlled oscillators(VCOs).

Showing high performance, high integration, low power, and multi-band performances, STW81100 is a low cost one chip alternative to discrete PLL and VCOs solutions.

STW81100 includes an Integer-N frequency synthesizer and two fully integrated VCOs featuring low phase noise performance and a noise floor of 153dBc/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 820MHz-1100MHz, the 1640MHz-2200MHz and the 3280MHz-4400MHz bands.

The STW81100 is designed with STMicroelectronics advanced 0.35µm SiGe process.
