PCBA 4.16
A two-layer FR4 PCB with 1 mm standard thickness is used. The PCB size is 25.4 mm x 17.9 mm.
There are 38 connection pads which are made as castellation (1/2 open drill) with 1.27 mm pitch.
The PCB layout is shown in Figure 15 and the fabrication parameters are given in Table 8.
The schematic diagram and BOM of the QFN48 antenna module are presented in Figure 16 and
Table 9, respectively.
