I want to generate a pulsed chirped waveform of 20 microseconds duration and linear FM from 50 to 100 MHz. This will be a triggered event, at roughly 25 Hz.
What is the best DDS EVM module for this application?
Here is a link to the appropriate product selection guide: DDS Product Selection Guide
If you would rather not use the link, then go to www.analog.com. Click on the PRODUCTS tab. On the left side will be a navigation pane (CATEGORY). Click on RF & Microwave. A list of selections will pop up. Click on Direct Digital Synthesis. This opens a product selection guide.
Choose a device that has "Yes" in the "Sweep Accumulator" column and at least 250MHz in the "Clock Input (Max) (Hz)" column. Of course, you must pay attention to the other columns to make sure the other parameters meet your needs.
