The BGA2815 datasheet says it is an amplifier for frequencies from DC to 2.2 GHz. But there is no spec for the gain at frequencies below 250 MHz, and figure 9 shows the gain dropping substantially around 100 MHz and lower. Is that drop real, or related to the AC coupling in the test setup? Is there any spec / data on what the gain is at, say, 10 MHz?
I hope all is great with you.
I am afraid that we do not have such data characterized, I mean at 100MHz or lower. This is a consumer type typically used for IF amplifiers in the 200 … 2150MHz range.
In case it is useful for you, we have S-parameter data from 20MHz onward, no models for this BGA28xx series devices.
