摘要：
In a diversity receiver, each of first and second diversity branches includes an antenna and a high-frequency amplifier coupled thereto. A diversity decision circuit is coupled to the outputs of the amplifiers to generate a switching control signal identifying one of the outputs of the diversity branches having a higher field intensity value. A power switching circuit is provided for coupling a voltage source to one of the amplifiers according to the switching control signal so that power supply to the other amplifier is cut off.
