Reliability of mmz09332bt1
Hello, I am not sure if this project is still active but I would like to ask your opinion on the reliability of the mmz09332bt1 power amplifier.
We have been using the same component in a UHF transceiver board and we have been having some weird results in terms of reliability on different aspects and occasions:
- In a few units the gain of the PA decreases drastically over time
- Sometimes, it blows up during transmission
- The PDC pin stops working (PA in constant standby mode)
- Pdet pin following power supply voltage and not working anymore
Despite our efforts, we cannot reliably reproduce these issues, but it happens quite often. In our design, we basically followed the application circuit provided in the datasheet, so nothing out of ordinary... We also contacted NXP support but we couldn't get a convincing answer/solution about this issue.
Do you have any feedback related to these issues? Have you experienced any of them during your tests?
Thanks in advance
