Title: Wireless unit
Inventor: YAJIMA HIROSHI
IPC: H04B1/3822
Filed: 2001-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a wireless unit that conducts time division transmission/ reception and simultaneous transmission/reception, has production of an unnecessary frequency component prevented in a transmission band and is small-sized. SOLUTION: A 1st frequency divider 121 frequency-divides the output signal of a transmission local oscillator 122 to generate a carrier signal. A modulator 102 modulates the carrier signal with orthogonal base band signals (I, Q) to generate a modulation signal. A transmission frequency converter 103 applies frequency conversion to the modulation signal by using the output signal from the transmission local oscillator 122 to generate a transmission signal. Since the frequency closest to the frequency of a transmission signal among harmonics in the modulation signal agrees with the frequency of the transmission signal, no disturbance is caused. Since a filter to eliminate the harmonics in the modulation signal is made unnecessary, the wireless unit can be downsized.
