Fig.22 Printed-circuit board and component layout for 225 MHz class-AB test circuit.
The circuit and components are situated on one side of the PTFE fibre-glass board, the other side being fully metallized to serve as an earth.
Earth connections are made by means of copper straps for a direct contact between upper and lower sheets.
