Classification: H04B

Abstract:
1. An integrated radio circuit comprises: a receiver section operably coupled to convert inbound radio frequency (RF) signals into inbound baseband signals; a transmitter section operably coupled to convert selected outbound baseband signals into outbound RF signals; analog to digital converter section operably coupled to convert the inbound baseband signals into inbound digital baseband signals; digital to analog converter section operably coupled to convert outbound digital baseband signals into the outbound baseband signals; digital baseband processing module operably coupled to convert selected inbound digital baseband signals into inbound data and to convert outbound data into outbound digital baseband signals; first dual function input/output (I/O) module operably coupled to provide the inbound digital baseband signals as the selected inbound digital baseband signals to the digital baseband processing module when the integrated radio circuit is in a normal mode of operation and to provide test inbound digital baseband signals as the selected inbound digital baseband signals to the digital baseband processing module when the integrated radio circuit is in a test mode; and second dual function I/O module operably coupled to provide the outbound digital baseband signals to the digital to analog converter section when the integrated radio circuit is in the normal mode of operation and to output the outbound digital baseband signals when the integrated radio circuit is in the test mode.
