How It Works

This product provides a stable, protective operating environment for internal components through the metal cavity structure, utilizing glass-to-metal hermetic sealing to achieve hermetic packaging of electrical leads, enabling input/output signals to complete transmission and filtering processing in a sealed environment.

External signals enter the internal filter structure through the pins for frequency selection or signal processing, then output through pins on the other side, achieving stable electrical signal transmission while the cavity structure provides shielding and mechanical protection.
