Abstract: Ceramic cavities 1a and 1b have upper and lower open faces and contain dielectric cores 2a and 2b formed integrally therein. The ceramic cavities 1a and 1b are sandwiched between upper and lower panels 3 and 4 at the upper and lower open faces, respectively, of the ceramic cavities 1a and 1b via grounding plates 5a and 5b and grounding plates 6a and 6b, respectively, and the upper and lower panels 3 and 4 are fixed by screws. Based on this structure, a problem of an unreliable joint part between an open face of a ceramic cavity and a metal panel connected directly to each other by soldering and the problem of increase of the number of components of a structure in which a printed circuit board is mounted to the open face of the ceramic cavity by using grounding plates can be overcome, even when the ceramic cavity has an open face formed in a complex shape.

Abstract: A calibration circuit for calibrating the input data path of a digital circuit is disclosed. A simple string of a repeating data pattern such as, e.g., “1100,” is sent on the data path. The digital circuit captures the data using a clock signal, examines the data signal for the predetermined pattern and adjusts a delay applied to the data signal until the predetermined pattern is recognized. Then the delay is further adjusted until the predetermined pattern is no longer recognized indicating that an edge of the eye of the data is near a clocking edge of the clocking signal. The delay applied to the data signal is then further adjusted by a predetermined amount to position the clock edge near the center of the data eye.
