|Embedded Discrete High K Capacitor Characterization in LTCC|
|Keywords: Embedded Capacitor, LTCC, High K Thick Film|
|This paper will discuss in detail the measurement results of the embedded discrete high K capacitors when fabricated within a Low Temperature Co-fired Ceramic (LTCC) structure. It will cover design rules and typical measured capacitor values and ranges which use high K thick film formulations of K ~500 and K ~1800 with X7R characteristics when embedded within the LTCC circuits. These capacitors could be utilized as biased and decoupling capacitors; near and around MMIC’s and IC’s instead of using surface mount capacitors or integrating them in the IC technology. Details of the properties of the dielectric materials, circuit functional designs and functional properties of the circuits will be discussed, along with processing details and recommendations.|
