ABSTRACT:
An integrated radio circuit includes a receiver section, a transmitter section, an analog to digital converter section, a digital to analog converter section, a digital baseband processing module, a first dual function input/output (I/O) module, and a second dual function I/O module. The first dual function input/output (I/O) module is operably coupled to provide inbound digital baseband signals as 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. The second dual function I/O module is operably coupled to provide 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.
