Wideband LNA

Hi,

I was checking for wideband LNA from 100Hz to 900 MHz. I found AD5530 as a useful choice. I think that is the sole of that type. Does AD has a similar wideband amplifier with more gain .( > 20 dB)

    We don't have anything in that form factor (i.e. 50 ohm single-ended in/out) that has a gain of 20 dB and covers that frequency range.  One option that might fit would be a differential amplifier. ADL5565, for example, will operate down to dc and has a 3 dB bandwidth of 6.75 GHz (www.analog.com/adl5565).   It's optimized for differential drive but the input can be driven single-ended.
