A key component of microwave telecommunication systems is the power amplifier. It is typically the amplifier’s linearity, output power, and efficiency that drive the communication system’s link performance, power budget, and thermal design. Balanced circuits are used to connect the circuit effectively and to analysis the power level and reduce the overall noise accurs level. Our proposed branch-line coupler consists of two parallel transmission lines physically coupled together with two or more branch lines between them. The band pass filter design is used to remove the frequency loss in certain required frequency range coverage. The narrow band process is to effectively analysis the required frequency level. The balanced band pass filter design is present a various shape in resonator antenna model and to cover the maximum gain level. A balanced circuit is to implement the balanced line section in any electrical and radio communication signal. This line is present in transmission process between two points. The band pass filter circuit performance is based on connection between resistor and capacitor combination . This design is to effectively remove the noise occurrence level. Dielectric resonator antenna design is work is higher frequency level and to cover the bandwidth level. This type of dielectric resonator antenna design is to perform the low loss process. In this architecture, our work is to design a narrow band based band pass filter design using rectangular dielectric resonator antenna. This antenna design is to increase the frequency gain level. Existing system is to design a dual mode multilayer filter design using dielectric resonator antenna design. The existing design is to analysis the bandwidth allocation level. Proposed design is to narrow band pass filter using resonator dielectric antenna. This design is to implement the balanced dielectric antenna methodology. This design is to modify the substrate integration module and to satisfy the narrow band frequency response process. This process is to improve the differential communication system performance level.
