SURFACE MOUNTING DEVICE OF DRO

摘要

PURPOSE: A surface mounting device of a DRO(Dielectric Resonator Oscillator) is provided to couple easily and simply a ceramic DR mounted on a substrate to solder on the substrate through an electrode laminated on a bottom of a spacer connected to the DR to prevent the floating of the DR as well as acquire a statable oscillation frequency characteristic. CONSTITUTION: A spacer(130) is integrally connected to a bottom of a ceramic DR(120) to be mounted on a substrate(110). The spacer(130) of the DR(120) is mounted on a DR coupling part(140) of the substrate(110) on which patterns(150) are formed. Solder(160) is coated on the center of the coupling part(140) of the substrate(110). An electrode layer(170) is formed on a bottom of the spacer(130) of the DR(120), thereby being coupled to the solder(160).
