Abstract
A high-frequency semiconductor device includes a microwave monolithic integrated circuit having first and second passive element sections each having at least one passive element as well as an FET. The FET has a gate connected to the first passive element section and a drain connected to the second passive element section. A bed configured as a plate of a conductive member is provided for mounting thereon the microwave monolithic integrated circuit. The bed has at least one opening or hole formed therethrough. The hole of the bed is provided at a specified position of the bed so as to underlie either one the first or second passive element section. With such an arrangement, it becomes possible to obtain enhanced performance.
