Abstract: PURPOSE: A testing device of a power amplification module is provided to improve production efficiency by testing the performance of two power amplification modules using two switches, two couplers, and two high pass band filters. CONSTITUTION: A first switch(130a) receives high frequency signals from a first power amplification module(110a) and a second power amplification module(110b) and selectively output one signal. A first high pass filter(150a) outputs the high frequency signal to the harmonic high frequency signal input port of a spectrum analysis device. A first coupler(140a) outputs the signal inputted from the first switch to a basic high frequency signal input port of the spectrum analysis device. The first coupler samples a part of the signal inputted from the first switch and outputs the sampled signal to the first high pass filter. A second switch(130b) receives a low frequency signal from the first power amplification module and the second power amplification module and selectively outputs one signal. A second high pass filter(150b) outputs the low frequency signal to the harmonic low frequency signal input port of the spectrum analysis device. A second coupler(140b) samples a part of the signal inputted from the second switch and outputs the sampled signal to a second high pass filter.
