    • A radio frequency filter is provided to increase the property of a filter by minimizing temperature variation by dispersing heat distribution and increase an contact area. A high power high frequency filter is composed of 2-way divider(10), a sub filter unit(12), and a 2-way combiner(14). The 2-way divider receives a transmission signal as an input and divides it into the same signal of 1/2 of the input signal. The sub filter unit receives two divided signal and passes a desired signal after removing an unnecessary signal since it is designed to have the same filter property. The sub filter unit is made of a first sub filter unit(FLT#1) and a second sub filter unit(FLT#2).
