ADL5391 - Single Ended Input.

Hi,

 

I recently bought an evaluation board of ADL5391.

I intend to use it as an ASK modulator, but my input signals are single ended.

 

XP => Low freq. ASK

YP => RF Carrier

 

The low freq. ASK signal has 400mVpp (0-400m), so in order to have at the output the desired signal, I must implement a configuration as described in Fig.19 of the datasheet. However, I am having a bit of trouble in getting the right resistor values.

 

Can anyone help me?

 

Thank you and regards,

scpires
