Other Parts Discussed in Thread: BQ79718V-Q1,
Tool/software:
Hello,
I am working on a new design that uses the cell monitor BQ79718V-Q1 and CC2662R-Q1. As reference design I have TI CSU V2.2A board physically and also the Altium project. After finishing schematics next step is routing the PCB.
For the PCB antenna I am using the same 2.4-GHz inverted antenna tuned to 50 Ohm following TI recommendations, app note below:
The app note says: "The results presented in this document are based on an antenna implemented on a PCB with a 1-mm thickness using standard FR-4 material"
It seems that the best wireless performance can be achieved using 1 mm final thickness pcb antenna. By the other hand, in eval kit CSU V2.2A Altium project, the stakup manager shows also 1 mm final thickness but in the mechanical layer it appears: Thickness: 2.0 mm +/-10%.
Also I've measured with a caliper the PCB thickness and it is 2 mm thickness.
Which is the correct thickness that I should use in the design?
Thanks in advance
