DIVERSITY RECEPTION CIRCUIT IN MOBILE COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a diversity reception circuit by which an image does not flicker by noise generation while searching for the antenna of excellent sensitivity. SOLUTION: This diversity reception circuit for comparing the output signals of a plurality of the antennas 6a-6d having respective boosters 5a-5d and selecting and using the antenna of the excellent sensitivity is provided with booster power supply current abnormality detection means 2a-2d and 3a-3d, for detecting the abnormality of power supply currents supplied to the respective boosters 5a-5d. For the antennas 6a-6d of the boosters 5a-5d supplied with the power supply current from booster power sources 1a-1d for which the abnormality is detected by the booster power supply current abnormality detection means, the output signals are not compared and use is inhibited.
