Hello,
I've to use a wideband LNA (like the ABA-53563 from AVAGO, it's a "internally 50-ohm matched silicon monolithic amplifier that offers excellent gain and flat broadband response from DC to 3.5 GHz").
My concern is that I've to pass the low frequencies as well, typically 50kHz. I calculated that I've to choose about 100nF as a capacitor. The problem is that this kind of capacitor has a weak behavior in the high frequency region (become a inductor).
What can I do ? Putting 100nF in // with 1nF for example? Somebody has a trick?
