ADL5801

Question

In datasheet, working frequency is mentioned as 10MHz to 6GHz, we want to know it will support close to DC?. If we feed less then 10MHz what will be the response.

Expect most specs to degrade. From the datasheet plots (Figure 21, 22 and 23), you can see that the return loss degrades significantly. Gain will degrade. You will also need to use external baluns that can handle your new low frequency (or you can operate single ended). Honestly if you want to operate at or close to dc, I would recommend you use a multiplier or an IQ modulator or demodulator.)
