Scott, https://www.minicircuits.com/pdfs/MAR-1+.pdf gives a part layout.
My recollection is to just lay the arms down on the pads and solder them like a SMT part. Caution: Part is static sensitive.

Arrgh. Where to begin. All was going well until "installing" U1 MAR-1 MMIC. Initial inventory of said kit was missing U1 MAR-1 MMIC. FWIW, there are no part numbers and no pictures in the pdf manual. So I emailed parts@elecraft and they sent me E600080 MAR-1 MMIC in a plastic bag. Upon inspection of this part during the build 2 weeks later it did not look like a solderable part, there were no leads for the thru holes. It appeared to be just plastic with a raised "+" on one side and two holes on one end. So I emailed parts@elecraft and said there has to be a mistake/problem and could they please check again and send the correct part that was solderable. I received the second E600080 MAR-1 MMIC. Meet the new boss same as the old boss... the parts were identical. Upon closer inspection under magnification there is a "part" located inside the "+". So cut it out and it is a very small black cylinder with 4 "arms" 90deg apart. If this is the correct part then I'll send back the first one they sent me. But here is the problem. The Ngen PCB Rev B (which is the PCB that I have) has 4 "thru holes" for installing U1 MAR1 MMIC and there are no leads from E600080 to solder it to the PCB. There are 4 "arms" but it is unclear to me how these "arms" are to be soldered to the board. Unless I solder wires in the 4 thru holes in the PCB and thence to the "arms" of E600080 I have no idea how to solder this part to the PCB. The pdf manual does not say anything about soldering wires into the thru holes and thence to the "arms". http://www.elecraft.com/manual/E740057_N-Gen_Manual_Rev_D.pdf I'm hoping someone else has built this module kit lately and figured it out or Elecraft is going to have to give me some guidance on how to solder this part to the board because it sure is not obvious to me.
