Fig.9 Component layout and printed-circuit board for 860 MHz test circuit.
The circuit and the components are situated on one side of the PTFE fibre-glass board, the other side being fully
metallized to serve as earth. Earth connections are made by means of hollow rivets, whilst under the emitter leads Cu
straps are used for a direct contact between upper and lower sheets.
