While testing a power amplifier I realized that there was not transmission at all. After checking the software, the connections and the power amplifier, I confirmed that my HackRF was broken. It was able receive but not to transmit. More precisely, I was not able to transmit when configuring the HackRF with medium-high TX power. However it worked when configuring the HackRF to transmit with low power.
A fast check in the schematics confirmed my fears: the power amplifier stage was blown.
