Hi everybody!The XCVR2450 suports same-frequency full-duplex, which would be perfect for radar applications. It uses a MAX2829 802.11 world-band
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 between tx and rx (Whole daughter board: transceiver,amplifier and RF switch) ?Many thanks in advance,
If not: Does anybody know the time that XCVR2450 takes to switch from tx to rx state ?
Jorge.
transceiver chip, which has only a single VFO in it, so the RX and TX sides have to be on the same frequency.
The TX/RX isolation, based on reading the spec sheet for the switch, a HWS383, gives 29.5dB isolation for the 2.4Ghz range, and about
20.5dB isolation for the 5GHz side.
I suspect that your application will be just fine on this card, using full-duplex, same-frequency mode.
