Power Coupling
A suggested layout for power and ground connections is given in figure 4B below. Connections are made via separate voltage and ground
planes. The mounting posts are at case ground and should not be connected to circuit ground. The mounting posts are at case ground and
should not be connected to circuit ground. The ferrite bead should provide a real impedance of 50 to 100 ohms at 100 to 1000 MHz. Bypass
capacitors should be placed as close to the 10-pin connector as possible.
