Hi, everyone.
we are using waveform generator AD9833 to generate BB waveform for IQ modulator, as recommended anti-imaging filter need to be placed to reduce distortion from modulator.
According to CN 0304 Circuit Notes 0304 a CF op amp as op amp need to be used since the maximum current output is approximately 4 mA, actually AD8014 have been used, also another reason to use AD8014 for impedance matching as written in Circuit Notes " provides a low impedance drive source for a high quality 50 Ω filter"
* Do we need to use such this configuration in CN 0304 with AD9833? or another configuration or other type of op amp ?
Regards
thanks for your support
