The second local oscillator signal is generated by a second local oscillator generator of a second transceiver circuit.

An electronic component unit includes an accommodation member, electronic components, and a bus bar including a rectangular unit. The accommodation member accommodates the electronic components and the bus bar in an accommodation space portion of an inner space portion. The accommodation member has a dividing wall that forms divided space portions by dividing the accommodation space portion. The dividing wall is provided with a slit that communicates the adjacent divided space portions. The rectangular unit of the bus bar is exposed to the inside of each of the divided space portions, when the rectangular unit is held by being inserted into the slit. The electronic components that are individually accommodated in the respective divided space portions are connected to the rectangular unit being exposed.

The plurality of terminals are respectively provided with a plurality of switches that have independent states of supplying power to the terminals and are switchable in between. A plurality of conductor plates are provided in the connector opening in an attachable and detachable state, and are each configured to electrically connect at least two of the plurality of terminals. The plurality of conductor plates are coupled by an insulating member.

A dual power inlet for portable generators addresses the challenge of safely recombining split power outputs from generators. This apparatus is designed for home power backup, utilizing readily available power cords and provides a practical solution for safely harnessing the full power capacity of large portable generators. The dual power inlet features a first twist lock receptacle and a second twist lock receptacle for receiving two 50 A circuits, each connected to a three-pole relay to prevent reverse current flow. A terminal block combines these circuits into a single output. A 220/240 V coil relay ensures proper phasing by actuating only with a combined 240 V, preventing short circuits. The system includes a ground block for safety and can interface with a home electrical panel via either an interlock or transfer switch.
