Evaluation kit
An evaluation kit can be delivered upon request, including the following:
● 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
● Application programming interface (API)
Three different evaluation kits are available, each optimized for one of the following
frequency ranges:
● 1 GHz
● 2 GHz
● 4 GHz
When ordering, please specify one of the following order codes:

Description
STW81103-EVB1G
STW81103-EVB2G
STW81103-EVB4G
1 GHz frequency range - divider by 4 output optimized
2 GHz frequency range - divider by 2 output optimized
4 GHz 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 matching components
and the balun.
