Hi Gene, KB3ONA
As described into your Handbook at page 10.30 Chapter 10, the ferrite
bead is slipped over the drain lid of a GaAsFET to prevent a possible
autooscillation of your MGF-1402 and in your case a ferrite bead of
Fair-Rite no.43 material is expecially suitable for this purpose.
BTW

Hi,
I am looking for a hard copy, gently used, of the Proceedings. If you have
one gathering dust which you would be willing to part with, drop me a note
off list.

Hi Gene,
I don't have read the scematic yet (I will do later in the morning), but I
suppose your schematic is a common source LNA.
If it's so, the ferrite on the drain it's a choke, used as a bias tee to
isolate the RF portion of the circuit (the GaAs FET) from the power supply.
For this

As illness prevented me from attending Dick's memorial, I can't thank
you enough for posting this video.
Dick was great guy, wonderful to work with, both professionally (the

was at VITA) and within AMSAT. He was
