Hi Team,
In the datasheet of AMC7836, it says that the maximum capacitive load is 10nF. However, customer needs to add a cap larger than 10nF to reduce the memory effect of wide-band PA which can improve DPD performance. Could you provide the detailed circuit design of DAC output inside AMC7836 or the bold plot? Then customer can add some simple isolation circuit in the output to make it work with cap higher than 10nF.
In addition, what's the resistance of the resistor below? This resistor may make damage to the GaN PA during startup of power down. Customer need it for evaluation.
thanks a lot.
Best regards,
Yang
