    摘要： A demultiplexer has a common terminal, a transmission terminal, and a reception terminal, and furthermore includes a transmission filter connected between the common terminal and the transmission terminal, a reception filter connected between the common terminal and the reception terminal, and a phase shift circuit connected in series to the reception filter connected between the common terminal and the reception terminal. A node on the line from the phase shift circuit to the common terminal or the transmission terminal, and a node on the line from the phase shift circuit to the reception terminal are coupled via a reactance. Accordingly, it is possible to fundamentally reduce or eliminate the situation in which transmission signals from the transmission filter arrive at the reception circuit, and improve isolation.

    摘要： A filter has a filter section that is provided with a balanced input terminal including a terminal 1 and a terminal 2 and a balanced output terminal including a terminal 3 and a terminal 4, and that passes a signal in a passband out of input balanced signals, and a balanced-to-unbalanced converter that is connected between the filter section and a single terminal. In the filter section, the frequency transfer characteristics between the terminals 1 and 3 differ from the frequency transfer characteristics between the terminals 2 and 4.

    摘要： A duplexer includes a ladder filter and a multimode filter that are formed on the same surface of a predetermined substrate. In this duplexer, a first comb-like electrode of the ladder filter and a second comb-like electrode of the multimode filter have the same layer structure with the same film thickness. The first comb-like electrode and the second comb-like electrode are formed with single-layer films mainly containing aluminum. The relationship among the film thickness h of the first comb-like electrode and the second comb-like electrode, the center frequency f1 of the frequency band of the ladder filter, and the center frequency f2 of the frequency band of the multimode filter, is expressed as: 300≦h×f1≦480 300≦h×f2≦430.
