NJG1695ME7 - 10 - test pcb layout (top view) precautions [1] the dc current at rf ports must be equal to zer o, which can be achieved with dc blocking capacitor s (c1~c10). (however, in case there is no possibility that dc c urrent flows, the dc blocking capacitors are unnece ssary, 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 (c11) clos e 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 plane should be placed near by the pin connection. pcb: fr-4, t=0.2mm capacitor size: 0603, 1005 strip line width: 0.4mm pcb size: 53 x 40mm c1 c2 c3 c4 c5 c6 c7 c8 c9 c10 c11 pca pcb p1b p1a p2a p2b p3b p3a p4b p4a vctl1 vctl2 vdd paths frequency (ghz) loss (db) 1.0 0.50 2.0 0.84 pca-p1a, pcb-p1b, pca-p3a, pcb-p3b 2.7 1.10 1.0 0.46 2.0 0.77 pca-p2a, pcb-p2b, pca-p4a, pcb-p4b 2.7 0.97 losses of pcb, capacitors and connectors 1 2 3 4 5 14 13 12 11 10 6 7 8 9 18 17 16 15 pcb pattern through-hole (radius: 0.15mm) pin note2: the ground plane and the through- holes under tab, as shown in the picture, are not necessities. there is no pr oblem in deleting them in the practical pcb design, though i n such case beware that the gnd terminals (pin 10 and 14 as for this particular design shown in the picture) still need through- holes being located in their vicinities.
