1. A high-frequency module comprising:
- front-end sections of first, second and third communication systems having frequencies that are different from each other, the front end sections of the first, second and third communication systems being integrated together and including;
a diplexer arranged to couple a transmission signal sent from any of the first, second and third communication systems to an antenna during transmission and arranged to distribute a receiving signal sent from the antenna to any of the first to third communication systems during receiving;
a first high-frequency switch arranged to separate a transmission section for the first and second communication systems and receiving sections for the first and second communication systems;
a SAW duplexer arranged to separate a receiving section for the first communication system and a receiving section for the second communication system; and
a second high-frequency switch arranged to separate a transmission section and a receiving section for the third communication system.

Abstract
A high-frequency module includes a diplexer, first and second high-frequency switches, a SAW duplexer, first and second LC filters functioning as first and second filters, and an SAW filter functioning as a third filter. The module defines a unit that integrates front-end sections of first to third communication systems, a digital cellular system (1.8 GHz band), a personal communication service (1.9 GHz band) and a global system for mobile communications (900 MHz band).
