Claims

[Scope of utility model registration request]

a shield case in which a partition plate having a grounding strip is disposed within a compartment of a frame base to form first and second compartments, and a shield cover is attached to an opening side of the frame base, the shield case being disposed within the first compartment; and a high frequency modulator circuit wiring body disposed in the second compartment, wherein the ground strip of the partition plate is bent toward the first compartment. The tip of the shield cover is brought into elastic contact with the inner surface of the shield cover, and the second
A modulator with an RF switch, characterized in that an undesired high frequency signal is prevented from entering the first compartment from the compartment.
