Claims20
An apparatus comprising:
- at least one receiver having injection points and having at least an amplifier and a transformer;
- and
- a plurality of isolation switches coupled to injection points of the at least one receiver, the plurality of isolation switches configured to route a calibration signal generated by a transmitter to one of the injection points.
A method comprising:
- coupling generating a calibration signal using a transmitter;
- and routing a plurality of isolation switches to the generated calibration signal at injection points of a at least one receiver through a plurality of isolation switches, the at least one receiver and the transmitter are configured in a single chip having at least one amplifier and a transformer;
- and
- routing a calibration signal generated by a transmitter to one of the injection points using the plurality of isolation switches.
