solder them directly onto the board. All four leads should now be
connected. Again, make sure that the small “M” is closest to L1. This is
very important.
❒
31. Find U1, the MAR3 amplifier. This looks like Q2, which you have
just installed, but is a bit smaller and has a dot printed on it. The leg
nearest this dot should be towards the outside of the board (or towards
C7). Insert the two legs on each side of the dot into the board, mounting
the part on the underside of the board.
❒
32. Again, make sure that the leg nearest the dot is also nearest C7. If it
is mounted properly, solder the two remaining legs flat on the underside
of the board.
Congratulations! You have just completed your LPA1 Power Booster
Amplifier. Please take a few minutes to look over your kit and ensure that all
of the parts have been assembled correctly. Since a few of the parts may be
unfamiliar to you, you may want to be extra sure that they have been inserted
correctly. Also, make sure that you have soldered all of the top side
connections in the correct spots. If you soldered the wrong connections,
your project may not work. After you are sure that everything seems to be
properly installed, move on to the setup and testing section. You will need a
12 volt supply, your transmitter, and a receiver.
