Texas Instruments CC1352 x Johanson Technology 0900PC15A0036
Integrated passive components, known simply as IPCs, are devices designed with a complete circuit embedded into a single package rather than discretely placed on the PCB. With the advent of wearables and the overall miniaturization of electronic devices, it has become an ever-increasing priority among designers to reduce both size and complexity while maintaining comparable performance. In an effort to simplify the implementation of the TI CC1352R and CC1352P chipsets, Johanson Technology (JTI) and Texas Instruments (TI) have worked together to create a compact, matched solution for the TI CC1352R and CC1352P chipsets.
The 0900PC15A0036 is an IPC designed by Johanson Technology to specifically operate in conjunction with TI chipsets CC1352R and CC1352P. Pairing the two devices together cuts down the number of components required for impedance matching, balun transformation, and harmonic filtering. For solutions with an integrated antenna, the RF passive component count is reduced from 23 to 3.

In order to illustrate the change in BOM that the 0900PC15A0036 provides, Figures 2 and 3 show the difference in component count between the IPC reference design and discrete reference design. This reduction also leads to decreased pick-and-place costs.

Table 1 below summarizes the overall link budget of JTI’s IPC vs. the discrete solution at maximum output power. In addition, Monte Carlo method shows that the IPC exhibits much more consistent performance over mass production when compared to the varying tolerances of 20+ individual L/C components.
