| Abstract |
Frequency multiplier is a technique for generating a high-stability, low-noise signal source in microwave and millimeter-wave communication systems, and utilizes harmonic frequencies generated by non-linearity of active elements. Depending on the harmonic output frequency to be used, it is divided into Multiplier, Tripler, and Quadrupler. In this paper, we implemented the frequency Tripler using the pHEMT device with Wide bandwidth and high conversion gain. The tripler system was designed and fabricated to obtain a 7.2GHz output signal from a 2.4GHz input signal. Measurement result 2.4 / 7.2GHz frequency tripler operates with input power of 0dBm at 2.4GHz and output power 8dBm at 7.2GHz and conversion gain up to 8dB. The implemented 7GHz band Tripler can be applied to various systems such as defense network and sensor network. |
