<p>PROBLEM TO BE SOLVED: To provide a semiconductor device whose operation becomes stably by suppressing unwanted resonance. SOLUTION: This semiconductor device has a MMIC(monolithic microwave IC) chip 11, where at least one part of a transmission path is made of a coplanar line composed of a signal conductor 1a and grounding metals 2a1-2a3 and 2b1-2b3 positioned on both its sides. In this case, the grounding metal is divided into plural grounding metals 2a1-2a3 and 2b1-2b3, and moreover the divided ground metals 2a1-2a3, and 2b1-2b3 are connected with the others by conductors 5 and resistors 3.</p> |
