Problems solved by technology

[0005] However, known quadruplexers exhibit non-optimal performance with respect to separation level and insertion loss
In particular, quadplexers for carrier aggregation (CA) operating with frequency bands with at least a narrow gap between the frequency bands have degraded right skirt steepness and undesirably high insertion loss

Embodiment Construction

[0067] figure 1 An equivalent circuit diagram of circuit elements with a quadruplexer QPX is shown. The quadruplexer QPX has a first filter structure FS1 and a second filter structure FS2. The first filter structure FS1 has an input port TX1, an output port RX1 and a common port CP1. The second filter structure FS2 has an input port TX2, an output port RX2 and a common port CP2. The common port of the first filter structure FS1 and the common port of the second filter structure FS2 are coupled or connected to the common port CP of the quadruplexer QPX.

[0068] Furthermore, the first filter structure FS1 has a first filter element FE1 . The second filter structure FS2 has a first filter element FE1. Both filter elements FE1 have an input port IP1. The input port IP1 of the first filter element FE1 of the first filter structure FS1 and the input port IP1 of the first filter element FE1 of the second filter structure FS2 are electrically coupled or connected. The inductive...

Abstract

A quadplexer is provided that provides improved insertion loss and passband steepness. The quadruplexer includes a first filter structure with a first filter element, a second filter structure with a second filter element, and an inductive element electrically connected in series to a common port of the filter structure and the input port of the filter element.

Description

technical field [0001] The present invention relates to quadplexers, particularly quadplexer topologies, and to electrical components providing quadplexer functionality. Background technique [0002] A quadruplexer is an electrical circuit that can combine and / or separate different RF signals, each signal having its own center frequency. For this purpose, a quadruplexer has a common port and one input port or one output port for each individual signal. Typically, a quadplexer has a common port, two input ports, and two output ports. Via the input port, an input signal (eg, a transmit signal) can be received from the external circuit environment and can be directed to the common port. Via output ports (eg, receive ports), output signals may be directed from the common port to corresponding output ports and provided to the external circuit environment. [0003] The quality of a quadplexer depends on the level of separation, that is, the separation between the different path...
