MULTI FREQUENCY BAND RECEIVER

摘要

PURPOSE: A multi frequency band receiver is provided to share at least one mixer in signal processing of a homodyne type and a heterodyne type. CONSTITUTION: A plurality of input terminals(I1,I2) receives signals of different frequency bands. A plurality of mixers(11,12) is connected to the input terminals respectively. The mixers receive the signals of different frequency bands. The mixers down-convert frequencies of the input signals as much as a preset size. One output terminal(O1) outputs a baseband signal.
