The STMicroelectronics STW81100 is an integrat-
ed RF synthesizer and voltage controlled oscilla-
Description
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
μ
m SiGe process.
