Abstract (en)

[origin: EP0993063A2] The invention provides a duplexer (15) comprising: a frequency variable filter (13) switching between a first band and a second band by a voltage-controllable reactor D1; and a transmission/reception select switch (14) connected to an input/output terminal of an end of the frequency variable filter (13). The above duplexer is small and capable of efficiently eliminating harmonics of transmission signals generated by a transmission/reception select switch. <IMAGE>
