MMIC ELECTROMAGNETIC NOISE FILTER AND MICROWAVE INTEGRATED CIRCUIT DEVICE INCLUING THE SAME |
摘要 |
An MMIC(Monolithic Microwave Integrated Circuit) type electromagnetic noise filter structure and an RF IC device with the same are provided to minimize the volume and complexity of circuitry and to improve a noise removing efficiency by manufacturing nonlinear semiconductor elements and a noise filter as one piece. A dielectric thin film(42) is formed on an upper surface of a semiconductor substrate(41). A coplanar signal line(43) is formed on the dielectric thin film. Both end portions of the coplanar signal line are connected with input/output portions. First and second coplanar ground lines(44a,44b) are formed at both sides of the coplanar signal line on the dielectric thin film.
