Part Number: LMX2820EVM
Hi Team,
The customer have set up a test environment by referring to the development board manual, but the actual phase noise results differ by about 16dB from the results given in the manual.
The test environment is as follows:
Power supply: KEYSIGHT E36313A 3.3V/0.6A
Reference source: LEYSIGHT PSG 100M
Simulation software: TiCS Pro
Signal Analyzer: CEYEAR 4141F
Test frequency point: 6GHz
Test Phase noise Point: 10 KHz frequency deviation
The actual test result is -100dBc/hz@10khz and the theoretical result is -116dBc/hz@10khz. Why are the differences so great and is there any way to improve it?
Could you please help check this case and give some suggestions? Thanks.
Best Regards,
Cherry
