    摘要: A diplexer employed in communications equipment (such as mobile phones) can divide signals into two channels with a simple configuration without interference. In this diplexer, an inductor is connected between a π-type three-stage one polar low-pass filter and a common terminal as a first matching circuit, and a capacitor is connected between a one polar band-pass filter and a common terminal as a second matching circuit. Two layers of a high-dielectric layer (2a,b,c) and low-dielectric layer (1a,b,c,d) are laminated, said band-pass filter and said second matching circuit are formed in said high-dielectric layer, and said low-pass filter and said first matching circuit are formed in said low-dielectric layer. In this manner, interference can be prevented and the higher harmonics can be attenuated.

    摘要: Ein Hochfrequenzsignal wird über zwei Frequenzteiler (F1, F2) in drei Frequenzbänder zerlegt. Das obere und mittlere Frequenzband wird direkt mindestens einem er­sten Richtkoppler (R1) zugeleitet, während das untere Frequenzband über eine Einkoppelschaltung (ES), be­stehend aus einer Spule (L) mit parallel geschaltetem Kondensator (C) und seriell geschaltetem Widerstand (W), mit dem abgeschlossenen Richtkopplerende verbunden und in den Ausgang (A1) des Richtkopplers (R1) eingekoppelt ist. Durch eine derartige Schaltungsanordnung wird die Auskoppeldämpfung des Richtkopplers (R1) bei tiefen Frequenzen reduziert. Das mittlere und untere Frequenz­band wird von einem Differentialübertrager (DÜ) abge­zweigt und weiteren Richtkopplern (R2, R2n) vom oberen Frequenzband getrennt zugeleitet. Ein weiterer Frequenz­teiler (F3) sorgt für die Aufteilung der beiden Frequenz­bänder, und deren Zuleitung an die zweiten Richtkoppler (R2, R2n) entspricht der an die ersten Richtkoppler (R1, R1n).

    摘要: The present invention discloses an input/output apparatus of a multiplexer, including: a main tap and at least two branch taps of the main tap, where each of the at least two branch taps is configured to couple to a different resonant cavity in the multiplexer, and the at least two branch taps include a first branch tap and a second branch tap; a coupling polarity of the first branch tap is opposite to that of the second branch tap; and a coupling calculation frequency of the second branch tap is closest to a coupling calculation frequency of the first branch tap. The input/output apparatus of the multiplexer provided in embodiments of the present invention enables two channels with closest frequencies to use different coupling polarities. Because the coupling polarities are different, signals naturally do not interfere with each other, and signal interference between channels is eliminated in principle. The embodiments of the present invention further provide a corresponding multiplexer.

A reception filter (15) is connected between the antenna terminal (3) and the reception terminals (5 and 6). The transmission filter (20) and the reception filter (15) are each formed of an elastic wave filter. A resonant circuit (34) is connected between the antenna terminal (3) and a ground potential. The resonant circuit (34) includes a surface acoustic wave resonator (35) and a capacitor (C2) connected in series with the surface acoustic wave resonator (35). A resonant frequency of the resonant circuit (34) is positioned in a frequency band of an interference wave that causes intermodulation distortion to be generated.

    摘要: A filter (10) for controlling the return path loss in a multi-channel communication system having forward and return paths. The filter comprises a forward path filter network (36), and a return path filter network (38). The forward path network passes signals in the forward path, and includes at least one resonant circuit component, such as a capacitor, which is coupled to the return path network (38). The return path network (38) passes signals in the return path, and includes at least one resonant circuit, such as a series LC trap to ground. A combined resonant circuit is formed, at least in part, by the resonant circuit component of the return path network (38) and the resonant circuit component of the forward path network (38) (e.g. a combined series LC trap to ground). The return path network (38) further includes an attenuator network (40) which is designed to attenuate the signals in the return path frequency band.
