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:

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.
