Provided is a multi-function radar apparatus capable of measuring both a distance to a target object and a temperature of the target object with high accuracy. The unit core is opposite to the neighboring unit core on an electric steel plate in orientation, and its unit yoke has an elongated end extending from a central line connecting a center of a tooth to a center of a core formed by interconnecting a plurality of the unit cores, to be opposite to the elongated end of the unit yoke of the neighboring unit core in orientation. The receive interface circuit includes a traffic controller circuit for separating frames in the first stream of data into a first deoptimizable frame and a first non-deoptimizable frame, and a deoptimization front-end circuit coupled to the traffic controller circuit to receive at least a first portion of the first deoptimizable frame. The capacitor is connected between the resistor and another node.
