Description

The STMicroelectronics STW81100 is an integrat-

ed RF synthesizer and voltage controlled oscilla-

tors (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 syn-

thesizer 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 calibra-

tion over 32 sub-bands) and multiple output op-

tions (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 STMicroelectron-

ics advanced 0.35

µm SiGe process.
