| Outline of Final Research Achievements |
Since performance of the wireless systems will strongly depend on oscillators, the direct oscillation at operational frequency will be desired in the viewpoint of oscillation power. However, it is difficult to obtain the oscillation device with high power at deep millimeter wave frequencies, so that the multiplication type of oscillators have been studied. Such oscillators consist of the fundamental oscillator, the filters, and the nonlinear elements, and a simple test fixture is desired to evaluate the performance of these devices. With this in mind, a simple coaxial line-microstrip line transition has been proposed in this research. And moreover, the harmonic oscillation of the Gunn diode was demonstrated. Next, the PLL oscillator consisting of harmonic mixer, charge pump, and loop filter was devised by using the harmonic oscillator to stabilize the oscillation frequency.
