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

Three different evaluation kits are available, each optimized for one of the following

frequency ranges:

●

1GHz

●

2GHz

●

4GHz

When ordering, please specify one of the following order codes:

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.
