Can be MMIC. Prefer not to require choke in power feed as the self resonance and inductance required by low frequency end would limit the high end. Low end of bandwidth is flexible but 1GHz high end is a must.
Take a look at LTC6433-15 (www.analog.com/LTC6433-15)
Since I plan to use the amplifier from lets say as low as 30KHz to 1GHz a single value of choke would not cover that entire range as we have a self-resonance issue. That is the problem.
When you need very broadband operation, the best recommendation I can make is to take a look at using conical inductors which are broadband but bulky. Here is a link to some Piconics devices.
For your needs, the frequency ranges on these devices are on the high side (i.e. start at 10 MHz and operate to 10s of GHz). So if you could find some larger values, they might fit you needs better but will of course they will be bigger again. You could try to replace the inductor with a resistor but this is tricky and performance will degrade because you will be modulating the bias point. I don't think that this is something that we have experimented with on this part.
What about putting inductors in series having progressively increasing values so when one passes self resonance the next one takes over
Sounds reasonable but it's not something we have tried. By the way, we also have family of differential amplifiers, many of which are dc-coupled. Of course, if you are looking for a 50 ohm single-ended interface, you would need baluns on the input and output. And you are back to the problem of finding a wideband balun.
