I am seeing large, nearly 1 volt drops on the QN9021's VDD (with the DC-to-DC active) during transmits with TX gain of 0 dBm. Is this behavior normal?
Hi Jaime,
What is the power supply? A battery or other equipment.
Best Regards,
Mario
Normally, a small 3v lithium coin cell battery. But the drops are present with a bench top power supply as well.
Hi Jaime,
9020 MiniDK can be powered by CR2032.
Did you have the same issue on the MiniDK?
Best Regards,
Mario
