摘要： A small-size multi-frequency antenna duplexer using surface acoustic wave filters and capable of dealing with a plurality of frequencies. Each antenna duplexer comprises two surface acoustic wave (SAW) filters used for transmission and reception, respectively, and having different frequency pass bands; a phase substrate; and a package housing the foregoing filters and substrate. The pass bands of the antenna duplexers are different from one another. This multi-frequency antenna duplexer comprises a plurality of antenna duplexers. A respective package (14) contains a transmitting surface acoustic wave filter (11a,11b), a receiving surface acoustic wave filter (12a,12b) and a phase substrate (13a,13b). In this way, the size of multi-frequency antenna duplexer can be reduced.
