Abstract
A receiver/transmitter apparatus that promotes mass productivity and miniaturization. The receiver/transmitter apparatus is provided with a transmitter circuit having a first mixer for mixing a transmission signal and an oscillating signal, an oscillator for generating the oscillating signal, and a receiver circuit having a second mixer for mixing a received signal and the oscillating signal. The receiver/transmitter apparatus has the transmitter circuit formed on a side region of a front surface of a common substrate on whose rear surface a ground electrode is formed. The receiver circuit is formed on the front surface of the substrate, on the other side region, and the oscillator is formed on a center region on the front surface of the substrate, between the transmitter and the receiver.
