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…
When using ADL5530 for wideband operation can I use a resistor instead of an inductor for DC bias. My operation is from 500 Hz to 500 MHz and I assume with inductor in place, there will be some selectivity and may be I wont get the sufficient gain peformance throughout my band specially at the edges..
