I am looking for an digital controlled variable gain amplifier with BW >200MHz.
The amplifier had to have min. 256 steps and should be used in an 50R system therefore impedance match on in- and output are preferred. Max output power10->20dBm.
I can´t find any integrated amplifier there match these requirements. My best choice is AD8368and then use a DAC for the digital control.
Have I missed some? Any suggest will be appreciated very much
Thanks in advance
