This paper proposes an ultra-compact filtering power divider with a wide harmonic suppression band. In this design, the proposed (PD) in ideal case has 100% size reduction and infinite number of harmonics suppression. However, real case, 92% suppresses 2nd to 45th harmonics. The small-proposed is designed at 0.9 GHz. typical Wilkinson two long quarter-wavelength branches. new resonant series LC...

A power divider with ultra-wideband (UWB) performance has been designed. The quarter-wave transformer in the conventional Wilkinson power divider is replaced by an exponentially tapered microstrip line. Since the tapered line provides a consistent impedance transformation across all frequencies, very low amplitude ripple of 0.2 dB peak-to-peak in the transmission coefficient and superior input ...

This paper presents a six-port network over an ultrawideband (UWB) of 2–8GHz. Its key component is the six-port junction, which consists of a Wilkinson power divider and three 3-dB quadrature couplers. This six-port junction is accomplished in a low dielectric constant substrate (Rogers RT/duroid 5880). Multi-section impedance transformation is applied in the power divider, and the quadrature c...

a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

In this article, a systematic procedure is presented for the design of dual-band unequal-split Wilkinson power divider (WPD) with high frequency and division ratios. The methodology based on replacing impractical high-impedance transmission line in conventional cascaded T-section structures short-circuited stubs. proposed simple adopts distributed elements without reactive components to achieve...

A generalized two-way coupled-line power divider with extended ports for dual band is proposed in this paper. The power divider is composed of two section coupled-lines, one conventional transmission line, and an isolation resistor, and employs extension of a transmission line or coupled-line at each port. The design equations are obtained based on evenand odd-mode analysis, and analytical idea...
