    • In order to suppress losses, unnecessary radiation, and internal mutual interference produced in a connecting portion between a nonreciprocal circuit device and circuits to be connected thereto and to promote reduction in size and weight of the device, a nonreciprocal circuit device and its mounting structure are provided. Output terminals are disposed on a mounting surface (bottom surface) of an isolator and input terminals are disposed at a height higher from the bottom surface as much as the height of a module circuit board. The top surface of the module circuit board is provided with connecting pads for connecting to the input terminals of the isolator. The module circuit board is provided with a shield case which is connected to ground terminals protruding from a yoke of the isolator. A part in which the module circuit board is integrated with the isolator is mounted on a printed circuit board.

    • PURPOSE: A nonreciprocal circuit device and a communication apparatus are provided to directly connect to a balanced output circuit without interposing therebetween a balun, a hybrid circuit, or the like. CONSTITUTION: An isolator(1) includes a metal lower case(4), a resin terminal case(3), a central electrode assembly(13), a metal upper case(8), a permanent magnet(9), an insulating member(7), a resistor(R) and matching capacitors(C1-C4). The central electrode assembly(13) is arranged in such a manner that central electrodes(21-23) intersect each other at an angle of approximately 120 degrees in a mutually electrically insulated manner on the upper surface of a disk-shaped microwave ferrite member(20). The central electrode(22) has a connecting portion(28) at one end thereof and the central electrode(23) has a connecting portion(29) at one end thereof. A ground electrode(25) is connected to the other ends of the central electrodes(22,23). The common ground electrode(25) and the central electrodes(22,23) are arranged in a manner substantially covering the lower surface of the ferrite member(20).
