摘要： A compact and highly reliable nonreciprocal circuit device can be manufactured at low cost. Marking is clearly performed on a surface of the nonreciprocal circuit device. In a method of manufacturing the nonreciprocal circuit device, after components constituting the device are joined together, solder is applied at portions where the components are bonded with each other. The magnetic force of a permanent magnet is adjusted and then laser marking is performed on a surface of a metal case. Next, the nonreciprocal circuit device is heated to perform together solder bonding, thermal aging of the permanent magnet, and the removal of stains left due to marking. Then, after checking the characteristics of the device, delivery inspection is conducted to complete the manufacturing process.

摘要： A nonreciprocal circuit element includes a lower metallic case, a resin terminal case, a ferrite, a center conductor, an upper metallic case, a permanent magnet, matching capacitor elements and other elements. The center conductor includes center electrodes each having two lines extending from a ground electrode. The height of the top surface of each of the matching capacitor elements is lower than that of the top surface of the ferrite. Simultaneously, in at least one of the center electrodes disposed on the side surface of the ferrite, the edge thereof is located closer to the capacitor electrode of the corresponding matching capacitor element than the other edge thereof. Also, in a direction that is substantially perpendicular to the height direction of the ferrite, the bottom surface of the one edge is located farther away from the capacitor electrode of the corresponding matching capacitor element than the top surface thereof.

The transmitting and receiving apparatus having a transmitter and a receiver sharing a single antenna is configured as follows. A circulator is provided at a feed point of the antenna between the transmitting system and the receiving system. Also, a changeover switch is disposed between a terminating resistor connected to ground and a point where the circulator and the receiver are connected so that the changeover switch can be automatically switched to the terminating resistor in response to input power supplied from the transmitter during transmission.
