Ground connection
Whenconnectingthemoduletosystem ground:
• Preventnoiseleakagebyestablishingaverygoodground
connectiontothemodulethroughthehostconnector.
• Connecttosystemgroundusingthetwomountingholesat
thetopofthemodule(asshownin
Figure3‐1).
• Minimizegroundnoiseleakage intotheRF.
Dependingonthehost boarddesign,noisecouldpotentially
becoupledtothemodulefromthehostboard.Thisis
mainlyanissueforhostdesignsthathavesignalstraveling
alongthelengthofthemodule,orcircuitryoperatingat
bothendsofthemoduleinterconnects.
