Hi andrew, any plan for release a down converter can test up to 42 GHz ? this is the FR2 5G band.

if SM200A can produce a lite version, just narrow the frequency from 230MHz to 6GHz, I think the price also will drop more, we will consider to buy it for the developing.

thank you Andrew, the SM200A also no DSP inside, if we want to decode LTE signal (PCI, RSRP, RS-SINR etc), still use PC to do the analysis of IQ signal?

I have 2 BB60C for test now, could you please email me some specification and price for the SM200A ? please also consider the LTE decoding of sample rate. btw, the DRT price is not cheap.

thank you Justin, now, all my customer will NOT use the BPF again since as before they used DRT receiver (2-3000MHz), if the out of band noise will affect the in band testing, it is hard to use it to decode LTE signal for telecom use.

but when attached the antenna, even no signal band, the floor noise still increase to -112dBm, pls check the attched picture;

I also compare another wide band receiver, with or without antenna, a little difference of floor noise. same frequency and RBW setting.

thank you, it is, could you please tell me the difference of “auto gain”, “gain 3” etc?

if someone can do it, I can pay money to buy the software or source code.

thank you so much, I think this is the best SDR receiver for LTE decoding, others just for lab trial use, can not for real field use.
you may add another RF port then can use 2*2 MIMO function.
