Semiconductor integrated circuit

摘要

A pin layout which prevents degradation of a frequency characteristic of a low noise amplifier (121, 123) and a receiving mixer (118, 119) included in a semiconductor integrated circuit for the dual-band transmission/reception wherein the circuit of the low noise amplifier is provided in a position where a distance from the end of the pin outside the package of the low noise amplifier to the pad is the shortest; ground pins (104, 106, 108) of two low noise amplifiers and the high frequency signal pins are arranged respectively so as not to be adjacent to each other; the power source and ground pin of the low noise amplifier, and the power source and ground pin of the bias circuit are respectively separated; and high frequency signal wires do not intersect to each other.
