The ninth step,according to figure 12, figure 13 weldingwire.

The USB connection 3; power jumper 2, antenna line 1, a total of 6.

The tenth step, the two low pass filter coil is welded to thecircuit board, to coil distance wide and pin width, low pass filter section completed. (see Figure 14)

Figure 14

Conditional word can use frequency sweep meter test low pass.

The eleventh step,welding of SMA female head. (see Figure 15)

The twelfth step, the control in Figure 15, to check their own circuit board welding.

The thirteenth step, Test machine.
Thus, the circuit part welding and installation workbasically completed.

The USB socket to connect with the computer, the indicating lamp immediately lit up, the computer alsodetect its existence.

The fourteenth step, Installation shell.
After welding installation is completed, put into thealuminum box, if the PCB board to plug in, you can usethe PCB file in polish can be slightly.

At this point, the entire production is completed.
