Other Parts Discussed in Thread: AFE7950, AFE7950-SP
Tool/software:
Hi Team, we are having a requirement of generating/receiving two signals,
1. X Band(around 10GHz)
2. Lower frequency ( < 200MHz)
we want to use single AFE for above application.
The AFE7950 specification says that if supports minimum frequency of 600MHz.
we could see that AFE7950-SP can support 5MHz in Rx direction.
As a experiment, We have programmed the AFE7950 EVM to generate and receive at smaller frequencies(less than 200 MHz) and we could see a good waveform in both directions as shown below.
Tx direction:
Rx direction:
we are assuming that the AFE7950 EVM - port A is not tuned for lower frequencies, so that the amplitude is less.
Query:
can we use AFE7950 for carrier frequency of 150MHz(with bandwidth 10MHz)?
if we can, what kind of problems we may get(signal stability, more spurious, lower amplitude... etc.)?
Please guide us regarding above queries.
Thank you,
Obul
