摘要：
A simple planar resonator using a magnetostatic wave (MSW) excited by aluminum finger electrodes with two bonding pads has been realized on a YIG/GGG substrate with two reflection edges. The tunable MSW resonator chip (2 mm × 5 mm) exhibits a sharp notch filter response, as deep as 20-35 dB and a high loaded Q up to 2000, which was tunable over the microwave frequency range from 2 to 4 GHz. A small tunable oscillator (8 cm3) has been experimentally demonstrated using the MSW planar resonator and a silicon bipolar transistor integrated on a ceramic microwave circuit substrate. Microwave oscillation with spectral purity, at the same level as that of Y1G sphere technology, is observed at 3 GHz. The experimental results indicate the technical areas for improvement required to realize a practical oscillator configuration. © 1990 IEEE
