摘要：
A duplexer includes a high-frequency switch, an LC filter serving as a low-pass filter, and an SAW filter serving as a band-pass filter. The high-frequency switch includes diodes, capacitors, and transmission lines. The LC filter includes capacitors and transmission lines. The high-frequency switch and LC filter are built into a multi-layer ceramic substrate, while the diodes of the high-frequency switch and the SAW filter are mounted on the substrate. The substrate is made of a low-temperature-baked ceramic material.
