| Abstract(in English) | In order to obtain high output power in higher frequency range such as millimeter wave, an input gate network for second harmonic FET oscillators has been investigated. In the frequency doubler, by using the input network which matches the gate terminal to signal source impedance for fundamental component and has pure reactance at both second and third harmonic frequencies, considerably high output power of second harmonic component was obtained compared with the case using a simple 50Ω line as an input network. The same input network was implemented with the second harmonic oscillator with the fundamental oscillation frequency of 4GHz, and high output power of second harmonic was obtained as 26mW. |
