Can somebody point me to characteristic data for the S3B module blocking performance.
I have a situation where the XCTU spectrum analyser is showing in band signals of -70dBm across the band where my handheld spectrum analyser is showing <-100 for the same RBW. I have 880 MHz cellular at -60 and 940MHz cellular at similar power levels and it appears this is the only source of noise, so it looks like this is the issue. I'm using 915-928MHz in AU.
In short has anyone got experience with this RF performance? Or are there any characteristic data that can help me understand this. It seems this part is using the ADF chipset which has decent blocking performance, so I'm thinking that perhaps there is an LNA before the chipset that could be worsening this? Is there a SAW filter inside?
