摘要 |
<p>A microwave multi-stage amplifier having amplifiers (5, 6) disposed on both sides of a partition (7) integrally formed in a shielding case, and an upper cover (11) fastened to the partition (7) with screws. The space in the case (8) is divided into two to suppress the generation of surface wave modes propagating in a dielectric substrate. Accordingly, the isolation of the amplifiers can be secured. <IMAGE> <IMAGE></p> |
