     2. Description of the Prior Art 
     In general, compact and high-performance components that constitute an RF module are required for multi-functionality and multi-band functionality in electronic devices that are capable of communication, such as a smart phone, a tablet PC, a portable multimedia player (PMP), a personal digital assistant (PDA), a laptop personal computer (PC), and a wearable device (e.g., a wrist watch, a head-mounted display (HMD), etc.). 
     SUMMARY 
     A duplexer is connected to an antenna and separates transmission frequency and reception frequency to perform a function of supporting two-way communication. 
     In the related art, in cases where the separation band between transmission and reception frequencies is small, or transmission and reception frequency bands are wide, a plurality of duplexers have to be used to cover frequencies in all bands so that it is difficult to make an electronic device compact. 
     A communication device and an electronic device that includes the same, according to various embodiments of the present disclosure, may provide a duplexer that can change a transmittable/receivable frequency band according to frequencies, thereby simultaneously implementing an improvement in the performance of separation between frequency bands and an improvement in insertion loss. 
     A communication device, according to various embodiments of the present disclosure, may include: a communication module configured to discover a network capable of communication; a processor configured to identify a first frequency band of the network and to output a control signal for changing a pass band of a band pass filter; a multiplexer configured to change the pass band of the band pass filter to correspond to the first frequency band of the network, and a tunable tuner circuit configured to change an impedance thereof according to the control signal. 
     A method for communicating in an electronic device, according to various embodiments of the present disclosure, may include: discovering a network capable of communication, identifying a frequency band of the network, generating a control signal for changing a pass band of a band pass filter, and changing the pass band of the band pass filter to correspond to the first frequency band of the network by changing an impedance of a tunable tuner circuit according to the control signal. The communication device and the electronic device that includes the same, according to the various embodiments of the present disclosure, include the duplexer that can change a transmittable/receivable frequency band according to frequencies, which makes it possible to minimize the number of used components and to reduce the size of the components.

It will be exemplified that the frequency band supported by the network is band  28 , which is the long term evolution (LTE) support frequency band. 
     In graph  1103 , comparing the frequency range of 718 MHz to 748 MHz (solid line), which is a high-frequency region of the transmittable frequency band of band  28 , with the transmittable frequency band (dotted line) of the transmitting end (TX)  410 , it may be identified that the transmittable frequency band (dotted line) of the transmitting end (TX)  410  covers the band of 718 MHz to 748 MHz (solid line), which is a high-frequency region of the transmittable frequency band of band  28 . 
       FIGS. 12A and 12B  are graphs depicting receivable frequency bandwidths of the electronic device  200 , according to one embodiment of the present disclosure. 
       FIG. 12A  is a graph depicting a receivable frequency band of the receiving end (RX)  420  of the electronic device  200  in a low-frequency region of the receivable frequency band supported by the network. It will be exemplified that the frequency band supported by the network is band  28 , which is the long term evolution (LTE) support frequency band. 
     In graph  1201 , comparing the frequency range of 758 MHz to 788 MHz (solid line), which is a low-frequency region of the receivable frequency band of band  28 , with the receivable frequency band (dotted line) of the receiving end (RX)  420 , it may be identified that the receivable frequency band (dotted line) of the receiving end (RX)  420  covers the band of 758 MHz to 788 MHz (solid line), which is a low-frequency region of the receivable frequency band of band  28 . 
       FIG. 12B  is a graph depicting a receivable frequency band of the receiving end (RX)  420  of the electronic device  200  in a high-frequency region of the receivable frequency band supported by the network. It will be exemplified that the frequency band supported by the network is band  28 , which is the long term evolution (LTE) support frequency band. 
     In graph  1203 , comparing the frequency range of 773 MHz to 803 MHz (solid line), which is a high-frequency region of the receivable frequency band of band  28 , with the receivable frequency band (dotted line) of the receiving end (RX)  420 , it may be identified that the receivable frequency band (dotted line) of the receiving end (RX)  420  covers the band of 773 MHz to 803 MHz (solid line), which is a high-frequency region of the receivable frequency band of band  28 . 
     Referring to  FIGS. 11A, 11B, 12A, and 12B , the electronic device  200  of the present disclosure, which uses a tunable duplexer, can efficiently support transmission/reception frequency bands while using a small system area in a case where the bandwidths of transmission and reception frequencies are wide, whereas the separation distance between the transmission and reception frequency bands is narrow, as well as in a general transmission/reception environment. 
     For example, in a case where the frequency band supported by a network is band  28 , which is the long term evolution (LTE) support frequency band, the transmittable frequency band ranges from 703 MHz to 748 MHz (45 MHz), and the receivable frequency band ranges from 758 MHz to 803 MHz (45 MHz). However, the separable frequencies of the transmittable and receivable frequencies are 748 MHz and 758 MHz, in which the difference therebetween merely corresponds to 10 MHz. In this case, the electronic device  200  of the present disclosure can efficiently support transmission/reception frequency bands while using a small system area. 
     It should be understood by those skilled in the art that the above described embodiments are only embodiments and are not restrictive since the embodiments can be implemented in other concrete forms without any change in the technical idea or essential characteristics of the present disclosure. The scope of the present disclosure is defined by the appended claims to be described later, rather than the detailed description. Accordingly, it will be appreciated that all modifications or variations derived from the meaning and scope of the appended claims and their equivalents are included in the range of the present disclosure. 
     The above-described embodiments of the present disclosure can be implemented in hardware, firmware or via the execution of software or computer code that can be stored in a recording medium such as a CD ROM, a Digital Versatile Disc (DVD), a magnetic tape, a RAM, a floppy disk, a hard disk, or a magneto-optical disk or computer code downloaded over a network originally stored on a remote recording medium or a non-transitory machine readable medium and to be stored on a local recording medium, so that the methods described herein can be rendered via such software that is stored on the recording medium using a general purpose computer, or a special processor or in programmable or dedicated hardware, such as an ASIC or FPGA. As would be understood in the art, the computer, the processor, microprocessor controller or the programmable hardware include memory components, e.g., RAM, ROM, Flash, etc. that may store or receive software or computer code that when accessed and executed by the computer, processor or hardware implement the processing methods described herein. In addition, it would be recognized that when a general purpose computer accesses code for implementing the processing shown herein, the execution of the code transforms the general purpose computer into a special purpose computer for executing the processing shown herein. Any of the functions and steps provided in the Figures may be implemented in hardware, or a combination hardware configured with machine executable code and may be performed in whole or in part within the programmed instructions of a computer. No claim element herein is to be construed under the provisions of pre-AIA 35 U.S.C. 112, sixth paragraph, or 35 U.S.C. 112(f), unless the element is expressly recited using the phrase “means for.”
