Abstract:
1. A semiconductor integrated circuit device for wireless communication formed on a semiconductor chip including: a receiving unit having an amplifier which is supplied a first signal to be amplified from outside of the semiconductor chip and having a frequency converting circuit which receives an output signal of the amplifier and converts to a frequency lower than the output signal, wherein a main surface of the semiconductor chip is provided with a plurality of electrode terminals along an edge portion thereof; wherein the amplifier has a transistor including a control electrode to which the first signal is to be supplied, a first electrode through which a signal is outputted in accordance with the signal supplied to the control electrode, and a second electrode to which a voltage is applied; wherein the control electrode, the first electrode and the second electrode of the transistor are connected to the electrode terminals through relatively short wirings therebetween, respectively; and none of the wirings are arranged to traverse the wirings respectively connected between a first of the electrode terminals and the first electrode of the transistor, between a second of the electrode terminals and the second electrode of the transistor, and between a third of the electrode terminals and the control electrode of the transistor.
