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.
What modulation scheme is being used? Do you have data you could share?
I am use 64-QAM for DVB-T system. The EVM test result is 10%. But I am forget save the figure. Do you need the test result figure ? Thank you.
Thank you for your help. I will re-try ADL5324 EVM test and to check measuring instruments setting. Thank you.
I test the ADL5324 couldn't match your report(ADL5324 EVM.pdf).
The ADL5324's EVM only reach 14dBm @ EVM<1%.
Could you tell me what happen?
Are you using the AL5324 evaluation board for the test, or, a board of your own design? By default the ADL5324 evaluation board is tuned for 2110 MHz - to 2170 MHz. Did you retuned the board for 800 Mhz operation as detailed in hte datasheet? Table 10 lists the necessary comoponents and Figure 43, shows the componnent placement.
