APPARATUS FOR GENERATING FREQUENCY SIGNAL

摘要

PURPOSE: A frequency signal generator is provided to generate all frequency signals corresponding to 1, 3, 4, and 6 multi-band orthogonal frequency division multiplexing band groups. CONSTITUTION: A reference frequency signal generator(100) generates a reference frequency signal for generating the frequencies of 1, 3, 5, and 6 band groups. A sub frequency signal generator(200) generates a sub frequency to be combined with the reference frequency signal. A mixer(300) is connected to the reference frequency signal generator and the sub frequency signal generator. A switch(400) switches a ninth frequency signal to a first divider(500) in response to a division selection signal. The first divider generates a tenth frequency signal by dividing a ninth frequency signal in half.
