POLAR LOW PASS FILTER AND DEMULTIPLEXER HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To place an attenuation pole in a desired frequency position.SOLUTION: A demultiplexer 1 includes in a laminated body 3: a low pass filter section 5 having in a series arm parallel resonance circuits 51-54 including capacitors C1-C4 and inductors L3-L6, and in parallel arms at least capacitors C5-C8; and ground conductors G1-G3. Pattern conductors constituting the capacitors C1-C4 face the ground conductors G1 etc. in a z axis direction.
