Abstract
A power divider having metal capacitors is disclosed to detect and divide a frequency signal. The divide includes a first capacitor including first and second electrodes formed at a first portion of a substrate, a second capacitor including first and second electrodes formed at a second portion of the substrate, a first metal line connected to the second electrode of the first capacitor, a second metal line connected to the second electrode of the second capacitor, a poly resistor connected to a contact area of the first capacitor and to a contact area of the second capacitor, and a third metal line connected to the first and second metal lines to divide a signal flown through the first and second metal lines.
