BIAS-T AND UNIT FOR ADJUSTING AN INCLINED ANGLE USING THE SAME

摘要

PURPOSE: A bias tee and an inclination angle control unit using the same are provided to physically separate a DC board part and an RF(Radio Frequency) board included in the inclination angle control unit, thereby improving inter-modulation distortion properties of an antenna. CONSTITUTION: A second substrate is located on the upper part of a first substrate. A signal line(302,304) is arranged on the first substrate. A coupling line(308) is arranged on the second substrate. A first PSR(Photo Solder Resist) layer(310) is arranged on the upper surface of the signal line. A second PSR layer(312) is arranged on the upper surface of the coupling line. The signal line and the coupling line are facing to each other.
