rf transceiver

Hey guys,

Lets discuss...

Is it possible for any RF transceiver chip(IC) to transmit and receive simultaneously?

If yes, name the chip and give me its working.
If no, why so?

Any CDMA or WCDMA transceiver transmit and receive simultaneously, due to full-duplex communication. Check for parts on: Infineon, Skyworks, Broadcom, Qualcomm.

CDMA indeed supports simultaneous transmission and reception.... but apart from them any other transceiver using any of the 802.11 or 802.15.1 or Zigbee standards..the transceivers using FHSS methods...etc,. can they do it simultaneously?

802.11 is a half-duplex protocol and cannot send or receive on the same time, but your initial question was, if “any RF transceiver chip” can do this job. So, the limitation is given by the protocol and not by the chipset.

CDMA and WCDMA do.
Such as QSC6285/QSC6270
