Re: [Discuss-gnuradio] XCVR2450 simple questions

Hi, Now it is clear enough that the XCVR2450 is not full duplex. The question I asked in my first post in the case it is not full duplex is still unknown for me. How long does it take to the board to switch from transmission mode to reception mode? In the data sheet I can read a picture called "

Jason, You are right my question about switching between tx and rx only makes sense if it is no possible to tx and rx at the same time. Since you told me it is possible to it at the same frequency (that means small doppler frequency shifts) the system looks promissing. I was afraid of wasting mos

Hi everybody! I read a lot of posts about XCVR2450 and I am still confused about its performance. I would like to set up a pulse doppler radar application around 2.4 GHz with USRP2 + XCVR2450 My simple questions are: Does XCVR2450 work in full duplex mode? If yes: Does anybody know the isolation
