A novel compact ultra-wideband (UWB) in-phase multilayer slotline power divider with high isolation is presented as a complement in slotline power divider field. The new structure proposed in this paper overcomes the shortcoming that power divider based on slotline almost cannot obtain high isolation between output ports. Based on the equivalent-circuit of microstrip-to-slotline transition and ...

This paper presents a broadband high operating frequency divide-by-2 frequency divider. This divider uses sourcecoupled logic (SCL) with two static loading master-slave D latches which achieves high input operating frequency, high input sensitivity and low power dissipation. This divider can work from 8GHz~ 27GHz and the input power is -40dBm@18GHz. The chip area is 735μm×480μm with only 4.6mW ...

An ultra-wideband (UWB) power divider is designed in this paper. The UWB performance of this power divider is obtained by using a tapered microstrip line that consists of exponential and elliptic sections. The coarse grained parallel micro-genetic algorithm (PMGA) and CST Microwave Studio are combined to achieve an automated parallel design process. The method is applied to optimize the UWB pow...

Abstract—This paper presents analysis and design of a wideband Wilkinson power divider for wireless applications. The design is accomplished by transforming the lengths and impedances of the quarter wavelength sections of the conventional Wilkinson power divider into U-shaped sections. The designed power divider is simulated by using ADS Agilent technologies and CST microwave studio software. I...

─ A novel ultra-wideband (UWB) out-ofphase four-way power divider is presented. To achieve a division over a large frequency range, Tjunctions formed by slotlines and microstrip lines are utilized. Based on the transmission-line equivalent-circuit method, we derive the design equations of the proposed power divider. Furthermore, all measured results are in good agreement with the predicted desi...

Filter plays an important role in communication systems. It is an electronic device that allows signal in certain frequency ranges to go through. In other words, filter helps remove all the unwanted frequency components in a signal. Generally, there are four types of filters: lowpass filter, highpass filter, bandpass filter and bandstop filter. Two filters have been proposed in my project. The ...

This paper describes a new Bagley power divider on a single-layer micro strip line that can reduce the occupied area. To va...

Abstract—This paper presents a novel tri-band unequal Wilkinson power divider. The proposed structure is derived from the conventional unequal Wilkinson power divider by replacing the quarter-wavelength branch lines and quarter-wavelength transformers with the extended T-shaped short stubs and three-section transformers respectively.

Abstract—A compact dual-band power divider for GSM/DCS applications is proposed in this letter. Novel planar artificial transmission lines are applied to miniaturize the power divider and achieve wideband response. The proposed dual-band power divider is about 37% of conventional one. The design principle, simulated and measured results are all discussed. The measured results show that good per...
