Abstract
A transmission and reception circuit includes a transmission circuit, a reception circuit, and a signal feedback path. The transmission path includes an output section, a signal generating circuit generating an in-phase component signal and an orthogonal component signal, and a transmission analog baseband circuit configured to perform digital to analog conversion of the generated in-phase component signal and orthogonal component signal. The reception circuit includes an input section, a reception analog baseband circuit performing analog to digital conversion of the transmitted in-phase component signal and orthogonal component signal, and a signal detection circuit that detects the analog-to-digital converted in-phase component signal and orthogonal component signal converted by the reception analog baseband circuit. The signal feedback path has a first end which is connected to the output section of the transmission circuit, and a second end which is connected to the input section of the reception circuit.
