Definitions

  • FIG. 3C is a schematic diagram of an exemplary transceiver in accordance with another embodiment of the present disclosure
  • FIG. 3D is a schematic diagram of an exemplary transceiver (partial view) in accordance with yet another embodiment of the present disclosure
  • FIG. 6 is an exemplary flow diagram of a process for generating and routing the calibration signal using an on-chip Tx signal path of the transceiver according to one embodiment of the present disclosure.
  • the two-tone calibration signal is generated on chip using the transmit (Tx) signal path including a transmit circuit 352 and power amplifier (PA) 354 during an idle mode of the transceiver 320.
  • Tx transmit
  • PA power amplifier
  • the Tx signal path should be configured to use either I or Q channel of the mixer and baseband filter, but not both.
  • the power of the two-tone calibration signal can be controlled by changing the gain of the Tx signal path. For sawless modes, the power of the tone signal can be as low as -14 dBm.
  • the generated two-tone calibration signal is routed to the Rx signal path at a point where the Rx signal path performance is not affected.
  • the two-tone calibration signal is injected at the input of LNA 340a (at point A) in the first receiver configured for GSM sawless Rx chain.
