HI All, Is it possible to use both the RX ports of an SBX daughterboard on an N210? If so could you please tell me how? I want one port (TX/RX) to receive a wired signal and have an antenna connected to the other one (RX2). The wired port will receive a tone at fc + 10khz. The antenna port will receive a tone at fc + 100khz. Hence, both are within the 40MHz bandwidth of the SBX. Thanks! -- Avinash

Hello Avinash: It's not possible to use both the TX/RX and RX2 simultaneously for RX. There is a switch from both antennas which connects to the single RX input on the SBX.

You could, however, externally sum up the two signals with an analog three-port.

Does this property (i.e. receiving on a single antenna only) hold for the WBX too ? I am asking because I don't think I see such a switch on the WBX's schematic. Please let me know, Thanks!

 three-port.

 antenna connected to the other one (RX2).

 port will receive a tone at fc + 100khz.

Certainly. The switch you're looking for is in the frontend , see wbx_fe.pdf.
