Product Number: ad8310
AD8310 has the six 14.3dB 900MHz amplifeirs in chip. and datasheet says " the maximum signal frequency can be 440MHz, but, because all the gain stages are dc-coupled, operation at very low frequencies is poosible." (page 9 of 24, last paragraph)
although chip has the six 900MHz amplifers, AD8310 has just a 25MHz video bandwidth. So, I think the bandwidth of the chip's output is 25MHz.
Then I have a question about bandwidth.
When and where bandwidth decrease? Of course, it will decrease with each stage, but at what stage does it have the biggest impact on reducing bandwidth?
1.six 14.3dB 900MHz amplifiers
2.nine detectors scells spaced 14.3dB
3.current mirror
4.amplifier (G=3)
