I have use ADL5324 andADL5320 to design RF front end , but I test the EVM is vey bad. Could you tell me ADL5324 and ADL5320 EVM specification, please? Thank you.
I believe there is a measurement setup issue going on. Source & VSA not synchronized or some other condition. I ran both ADL5320 & ADL5324 and have EVM at or below 1% until about 10 dB below the P1dB level. I use 64 QAM, Alpha 0.2, 5 MSPS symbol rate and an RRC filter. The frequency is 2140 MHz. This the default tuning for the evaluation boards.Attached is the data.
