Compact mobile duplexer are manufactured using six-section helical resonators by rejection design. Dimensions of MDF-6-75 duplexer allow its mounting into the same case with radio station. However, one should notice, that such duplexers are ineffective, when implemented in base stations or at the sites with compromised electromagnetic compatibility.
