LMH6502: Gain adjustment range

Part Number: LMH6502
Other Parts Discussed in Thread: LMH6503

Hi Team,

Can you please help us with our customer's inquiry below?

I have a question for LMH6502, and it's a wideband linear amplifier

In its datasheet, if you check the feature in page 1, it indicates that the adjustable range is 70db

Does it mean that the output of the amplifier will give me a 70db extinction ratio maximum?

More specific, if I have a voltage source of 80Mhz as the input, when LMH6503 is at the maximum gain, I get output 1. when LMH6503 is at the lowest gain, I got output 2. The extinction ratio would be 10*log(P1/P2)

P1 is the power: [(output1)^2/50].

Regards,

Danilo
