contexte

"This invention relates to electronic circuits, and more particularly to calibration and testing architectures for radio frequency integrated circuits."

"A radio frequency, RF, integrated circuit that enables accurate calibration, comprising a primary RF transmission path, a primary RF reception path, and at least one RF transceiver front-end circuit, wherein at least one RF transceiver front-end circuit includes a phase- attenuation core comprising a phase shifter circuit and a signal amplitude control circuit, and optionally includes an input/output circuit"

"at least one switchable internal calibration path coupled to the at least one RF transceiver front-end circuit and configured to convey, in a calibration mode, an RF test signal from the primary RF transmission path through at least a portion of the coupled at least one RF transceiver front-end circuit to the primary RF reception path"

"at least one switchable internal calibration path is a switchable cross-circuit calibration path between at least two RF transceiver front-end circuits and the primary RF reception path and configured to convey, in the calibration mode, the RF test signal from the primary RF transmission path through such at least two RF transceiver front-end circuits to the primary RF reception path"

"sets of internal switchable periphery cross-circuit calibration paths, each connected to the transmit path TX and the receive path RX of pairs of phase-attenuation cores by associated switches."
