I have a question for input resistance between AD8363 and ADL5902.
I’m wondering why are you changing from 50Ω to 2000Ω in comparing two products?
The input impedance is set primarily by an internal 50 Ω resistor connected between INHI and INLO.
Disadvantage: Using INHI (Pin 14), users can obtain the best dynamic range at frequencies up to 2.6 GHz. Above 2.6 GHz, it is recommended
that INLO (Pin 15) be used
The input impedance is set primarily by an internal 2 kΩ resistor connected between INHI and INLO
