摘要:
Input matching is achieved for a high-frequency range having a center frequency of 0.8 GHz by a capacitor and a coil in an input matching circuit, and input matching is achieved for a high-frequency range having a center frequency of 1.9 GHz by another coil in the input matching circuit. Output matching is achieved for a high-frequency range having a center frequency of 0.8 GHz by a capacitor and a coil in an output matching circuit, and output matching is achieved for a high-frequency range having a center frequency of 1.9 GHz by another coil in the output matching circuit.
