Evaluation Kit
Upon request an Evaluation Kit can be delivered. It includes:
● Evaluation Board
● GUI (Graphical User Interface) to program the device
● Measured S parameters of the RF output
● ADS2005 schematics providing guidelines for application board design
● STWPLLSim software for PLL loop filter design and noise simulation
Three different Evaluation Kits are available, one optimized for 1GHz frequency range, one
for 2GHz frequency range and the last one for 4GHz range.
While ordering please specify the following order codes:

Description
STW81102-EVB1G
STW81102-EVB2G
STW81102-EVB4G
1GHz frequency range - Divider by 4 output optimized
2GHz frequency range - Divider by 2 output optimized
4GHz frequency range - Direct output optimized
The three Evaluation Kits differ only for the output stage network and can be adapted from
one frequency band variant to a different one replacing properly the macthing components
and the balun.
