Abstract

In a wireless communication device (10), in a correction value calculating mode, a control unit (101) flips switches (108, 112, 117) to the "a" sides, a modulation processing unit (102) generates a CW signal as an I channel signal, a DAC (103) converts the digital CW signal into an analog CW signal, an LPF (104) eliminates the high-frequency component from the CW signal, a mixer (105) functions as an up-converter for up-converting the CW signal, a PA (114) amplifies the RF power of the CW signal, a mixer (109) functions as a down-converter for downconverting the CW signal, an ADC (118) converts the analog CW signal into a digital CW signal, a level detecting unit (119) detects the voltage level of the CW signal, a correction value calculating unit (120) calculates a correction value based on the detected voltage level, and a correction value storing unit (121) stores the calculated correction value.
