Most tripler research papers tend to design it with a band pass filter at the output terminal. A tripler with a band pass filter has a disadvantage in using a broadband frequency because the bandwidth of the target frequency is narrow. Therefore, as a solution to this problem, the topic of the thesis was to design a tripler with a wide bandwidth by applying a band stop filter to the output terminal.
In this paper, a tripler with a band pass filter and a band stop (notch) filter at the output terminal using a pHEMT device as an active device was designed, and then two triplers were simulated.
Comparing the characteristics of the two triplers, at the target frequency of 7.2GHz, the output power of the tripler with a band pass filter is 18.9dBm (conversion gain, 2.76dB), and the output power of the tripler with a band stop filter is 23.1dBm (conversion gain, 3.63dB). Therefore, the conversion gain of the tripler with the band stop filter is about 30% better than that of the tripler with the band pass filter. The bandwidth of the tripler with the band pass filter is narrow, and the bandwidth of the tripler with the band stop filter is about 2GHz from 6GHz to 8GHz centered on 7.2GHz, and it shows broadband characteristics. Therefore, when comparing the characteristics of the tripler with the band stop filter and the band pass filter, it can be confirmed that the tripler with the band stop filter is excellent.
