This paper presents the design and fabrication of a stand-alone high directivity coupler using high dielectric constant multilayer organic (MLO) technology. MLO is a low cost high density interconnect technology that allows for the realization of high Q and low loss inductor and capacitor elements that allow for the miniaturization of RF and mixed signal circuits. Q values above 300 have been measured for MLO with costs being lower than both LTCC and TFOS technologies. Low-loss lumped and distributed elements were realized using a novel multilayer build up process that supports both land grid array (LGA) and edge terminations. The couplers which support frequencies between 700 MHz and 2GHz exhibit coupling coefficients above 20db and isolation greater than 40db. The couplers can be combined with low pass harmonic filters in the same technology.

ABSTRACTAs the active matrix flat panel market continues to grow, manufacturers are constantly looking for ways of gaining an advantage in the marketplace typically through increased performance, expanded functionality and/or reduced cost. The continuing trend of larger panel sizes and higher resolution poses interesting challenges for manufacturers in the areas of image quality and brightness. In particular, it has been clearly shown that as pixel dimensions shrink, relative crosstalk coupling coefficients increase while the area available for pixel electrodes and storage capacitors (Cδ,t) decreases, so that charge compensation drive schemes must be employed to eliminate visual artifacts. One approach to minimizing crosstalk and flicker is to increase Cδ,t, however this requires increased pixel area, usually at the expense of brightness due to smaller aperture ratio. Depending on design and process flow, it may be possible to replace the typical Cδ,t, insulator, SiNx:H, with a material of higher dielectric constant thereby vastly improving electrical performance without sacrificing brightness.
