Abstract:
A semiconductor integrated circuit device for receiving operation of a mobile radio communication apparatus comprising:a sealing package enclosing a semiconductor chip and having four sides and being formed in rectangular shape in a plane view; a first low noise amplifier into which a radio frequency reception signal of a first frequency band is to be inputted; a second low noise amplifier into which a radio frequency reception signal of a second frequency band is to be inputted, the second frequency band being different from the first frequency band; another circuit; a first receiving mixer for the first frequency band into which an output signal from said first low noise amplifier is to be inputted; a second receiving mixer for the second frequency band into which an output signal from said second low noise amplifier is to be inputted; a first pad disposed on said semiconductor chip and electrically connected to said first low noise amplifier; a second pad disposed on said semiconductor chip and electrically connected to said second low noise amplifier; a third pad disposed on said semiconductor chip and electrically connected to said another circuit; a first input pin having a first pin end projecting to outside said sealing package and electrically connected to said first pad; a second input pin having a second pin end projecting to outside at the same side of said sealing package where the first pin end is projecting to outside and electrically connected to said second pad; and another pin having a third pin end projecting to outside at the same side of said sealing package where the first pin end is projecting to outside and electrically connected to said third pad, wherein said first and second low noise amplifiers, said another circuit, said first and second receiving mixers, said first, second, and third pads, said first and second input pins, and said another pin are monolithically integrated on the semiconductor chip, wherein said first and second pads are disposed at the same one of four sides of the semiconductor chip, wherein a distance between said first pad and said first pin end and a distance between said second pad and said second pin end are shorter than a distance between said third pad and said third pin end, and wherein said radio frequency reception signal of the first frequency band is to be applied to said first input pin and said radio frequency reception signal of the second frequency band is to be applied to said second input pin.
