Integrated 2 GHz mixer The AD9858 is a direct digital synthesizer (DDS) featuring a
10-bit digital-to-analog converter (DAC) operating up to 1 GSPS.
The AD9858 uses advanced DDS technology coupled with an
internal high speed, high performance DAC to form a digitally
programmable, complete high frequency synthesizer capable of
generating a frequency-agile analog output sine wave at up to
400 MHz. The AD9858 is designed to provide fast frequency
hopping and fine tuning resolution (32-bit frequency tuning …
