  • Microwave integrated circuit
    Patent number: 4967171
    Abstract: In a microwave integrated circuit, circuit elements such as microstrip coupled lines or interconnecting lines are formed on a separate substrate which is installed vertically between two halves of an input/output transmission-line substrate, or which is installed vertically on the surface of the input/output transmission-line substrate. Microwave integrated circuits with this configuration can be mass-produced at a low cost, can tolerate high applied power levels, and are smaller than conventional microwave integrated circuits.
