CERAMIC I-F TRANSFORMERS.
Abstract
Vibration tests were run on 4.3 mc resonators packaged in the micro-module configuration without adverse effects. Fabrication and packaging techniques were improved for 4.3 mc 1st overtone radial resonators. However, dimensional tolerances such as the thickness of the bond between micro-module wafers, appear to be critical. Packaging data is presented for a group of resonators. Equations of motion were solved for the asymmetrically excited radial vibrations of disks. The eigenfrequencies for these modes along with those of the previously identified symmetrical modes account for most spurious or unwanted responses in small diameter thickness resonant disks. In the development of uni-wafer filters, it was demonstrated that dot-resonators can be interconnected without adversely affecting their performance. Polarization requirements for the dot-resonator in terms of a range of action are discussed along with the effect of electrode thickness. (Author)
