4 Summary

As an alternative to the discrete reference designs as shown in Figure 1-2 the 10 dBm PA IPC component reference design has similar performance to the discrete reference design with a lower component count. 11 passives are required for the CC2652P 10 dBm PA port but by using the IPC, the component count is reduced from 11 to a single component which saves space and reduces pick-and-place assembly costs.

Figure 4-1 shows that the efficiency of the LAUNCHXL-CC1352P-4 10 dBm is 10.9 % and the 10 dBm PA IPC is 9.6 % which shows similar performance for a very compact design. This means that there will be a slight loss in performance when implementing the 10 dBm PA IPC compared to the standard reference design.

Figure 4-1 Comparison of Efficiency between the IPC and Discrete Solution

There are some clear advantages to the 10 dBm PA IPC compared to the discrete design. If the loss in efficiency is acceptable the 10 dBm PA IPC offers improvements with a more compact layout, reduced "pick-n-place" production costs, and an easy layout.
