|A couple of TRB members have told me the ground plane is very important. This week end I was listening to a lecture from a man who owns a company that makes and sells electronic gadgets. He suggest a layered construction. The RF on top with a ground plane under it and the power connects under the ground plane. He has the boards made using 4 layer methods. While it is a great method it doesn't lend itself to a build and modify person like me. So I adopted a different approach which may work for a galoot like me. I cut a thin slice from the end of a 2X4 board. It is about 1/8". I drilled the four corner holes of the board and prepared to mount it.
|I put copper tape on the bottom of the board to form a ground plane and a Vcc bus.
|The black line helps me know where to find a ground or Vcc. I tinned four pads to take the chip.
|Position the chip an apply a little heat to mount it to the board.
|The method presented was to create the DC circuit first so i soldered a 100k and a 10k resistor to produce the voltage for biasing gate 2. A second 100k resistor biases gate1.
|I put a capacitor on the input and output.
|A bypass capacitor on gate 2 to prevent cross modulation.
|Now for the test. Dip meter feeds a signal.
