摘要:
A diplexer employed in communications equipment (such as mobile phones) can divide signals into two channels with a simple configuration without interference. In this diplexer, an inductor is connected between a π-type three-stage one polar low-pass filter and a common terminal as a first matching circuit, and a capacitor is connected between a one polar band-pass filter and a common terminal as a second matching circuit. Two layers of a high-dielectric layer (2a,b,c) and low-dielectric layer (1a,b,c,d) are laminated, said band-pass filter and said second matching circuit are formed in said high-dielectric layer, and said low-pass filter and said first matching circuit are formed in said low-dielectric layer. In this manner, interference can be prevented and the higher harmonics can be attenuated.
