Abstract :
LTCC substrate material has been successfully used to fabricate a 4-GHz 20-dB stripline coupler with 20-dB directivity and a low second harmonic 4-GHz stripline edge coupled filter. These circuits provide mechanical, size, performance, and cost advantages when compared to stripline assemblies made from softboard or nonhomogeneous materials. Measured results for both circuits are presented and design recommendations are discussed.<>
