simplest possible rf amp
 

Hi - I am looking for a circuit diagram for the absolute simpleat possible rf amP that can go up to about 100Mhz - can anyone help please. Not looking fir quality - just the bare bones of something that works. Cheers Peter

Probably a MMIC, like a MiniCircuits ERA series, or one of the SOT89
parts for higher power.

All that needs is an input capacitor, and output capacitor, and a
pullup resistor to a positive power supply. 4 parts. Expect numbers
like 20 dB gain from LF to several GHz.

What became of the good old MAR8 ?

Another alternative is a DG MOSFET, with a RFC drain load the second gate
can be used as a gain control.

Do you mean a linear RF PA?

If you are looking for an RF pre amp to help on receiving, the MPF 102
has always been great.

If you are looking for something to boost a transmitter and don't want
to bother with quality, I wish you the worst of luck!

Might be easier to get an '88 from that old boatanchor scope gathering dust
in the corner.

That was a little harsh. The problem with sloppy power amps is that
they cause every one trouble, including the neighbors!

Married RF transistors are known to cause resonance issues, leaks, and
are always incorrectly biased, usually ending up in courts. I'd stick to
single RF amps.

In cascode it depends which one gets on top.

Didn't say they were good. Said they will do just fine, for the quick
and dirty amplification, to boost the 100MHz. neighbours conversations.
