Part Number: LAUNCHXL-CC1352P
Other Parts Discussed in Thread: CC1352P
Hi,
I have a question regarding the optimum load impedance of CC1352P chip. I am reading this APP note SWRA640F, in chapter 9, it listed the optimum load impedance of various chips, it says the optimum load impedance of CC1352P is 26+j25 Ω for 2440MHz fundamental of 2.4GHz PA path.
From my understanding, the load impedance of the chip is the impedance seen from the chip, so I did an experiment with Launchpad CC1352P-2. I took off the chip and did the measurement with below setup.
The impedance I saw from the VNA is different from the stated data from the APP note.
I am wondering if my measurement method is not right. Please advise. Thanks.
Regards,
Evan
