Embodiment Construction
[0012] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0013] like figure 1 As shown, the 4dB attenuator with a power capacity of 100 watts includes an aluminum nitride substrate 1, and a conductive layer is printed on the back of the aluminum nitride substrate 1, and the conductive layer is printed by printing silver paste. The front side of the aluminum nitride substrate 1 is printed with resistors R1, R2, R3, R4, R5 and silver paste wires 2. The resistors R1, R2, R3, R4, and R5 connect the silver paste wires 2 to form an attenuation circuit. The resistors R1, R2 , R3, R4, and R5 are all printed with a glass protective film 3, and the glass protective film 3 is used to protect the resistors R1, R2, R3, R4, and R5. Also be printed with one deck protective film 4 on the upper surface of whole circuit i.e. silver paste conductor 2 and glass protective film 3, on protective film 4, be printed with...
