Abstract
An RFID device provided at a transmission and reception circuit processes an RFID carrier signal belonging to a band of about 902 MHz to about 928 MHz or about 865 MHz to about 868 MHz to execute near field radio communication. An RFIC provided at a transmission and reception circuit processes a GSM carrier signal belonging to a band of about 824 MHz to about 894 MHz or about 880 MHz to about 960 MHz to execute mobile communication. A filter circuit provided at the transmission and reception circuit takes the band of about 850 MHz to about 940 MHz where RFID carrier signals appear as the pass band, and takes the band greater than or equal to about 1.2 GHz where a harmonic wave component of GSM carrier signals appears as the attenuation band.

(canceled)
A communication device comprising:
- a first communication system configured to communicate using a first communication signal with a first frequency band as a carrier frequency, and including a first radio communication integrated circuit configured to process the first communication signal;
- and
- a second communication system configured to communicate using a second communication signal with a second frequency band in a vicinity of the first frequency band as a carrier frequency, and including a second radio communication integrated circuit configured to process the second communication signal;
- wherein
- the first communication system further includes a filter circuit with the first frequency band as a pass band, and configured to attenuate a harmonic wave component of the second communication signal.
