We have previously supplied QPA2213 from QORVO. My schematic design is attached. The voltage shown as -4V can change and can be selected according to the desired voltage value. Unfortunately, QPA2213 does not work as we would like. For example, although we give a signal at a frequency of 8 GHz with an amplitude of -30 dBm to the QPA2213 integration, completely independent signals are output, but the signal we want does not increase. On the contrary, when I bring the QPA2213 Vg voltage to a level to draw 360 mA, the reflected signal increases. Do I have any mistakes in the schematic design?
One of our FAE team will be in touch today to discuss it.
