NJG1692NB2 - 8 - pcb layout (epcsp10-b2) (top view) pcb layout precautions [1] the dc current at rf ports must be equal to zer o, which can be achieved with dc blocking capacitors (c1~c6).(however, in case there is no po ssibility that dc current flows, the dc blocking capacitors are unnecessary, i.e. the rf signals are fed by saw filters that block dc current by nature, etc.) [2] to reduce stripline influence on rf characteris tics, please locate the bypass capacitor (c7) close to vdd terminal. [3] for good isolation, the gnd terminals must be c onnected to the pcb ground plane of substrate, and the through-holes connecting the backside ground pl ane should be placed near by the pin connection. gnd via hole diameter : = 0.2mm pkg terminal pcb pkg outline
