چکیده
In this paper, a novel Wilkinson pulse combiner (WPC) is proposed for the combination of Gaussian signals. The WPC requires very wide bandwidth, small size and high port isolation. To improve operating design adopts form eight-section WPC. Eight capacitors are connected in series with isolating resistors each section. After capacitive loading, isolation between input ports significantly improved at low frequency. Consequently, bandwidth has been increased from 13:1 to 31:1. Compared conventional same reduces by 40%. addition, all well impedance matched insertion loss frequency band less than 0.5 dB. verify feasibility design, prototype was fabricated measured. Experiment shows that more advantageous generate dual-Gaussian

A Novel Design of a Low Cost Wideband Wilkinson Power Divider
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...
متن کاملA Novel 36-pulse rectifier with low kVA rate to reduce harmonic input current distortion
The increase in the number of pulses in multipulse rectifiers leads to a reduction in harmonic current distortion. But this increase in the number of pulses leads to an increase in kVA, cost, and complexity of the multi-pulse rectifiers. As a result, in industrial applications, 12-pulse rectifiers are mainly used due to their lightweight, simple transformers, and low kVA rate, and low cost. The...
متن کاملA Low Power Low Voltage Rail to Rail Constant gm Differential Amplifier with 150 dB CMRR and Enhanced Frequency Performance
This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...
متن کاملA Novel Low-profile Wideband Uhf Antenna
Abstract—In this paper, an ultra high frequency (UHF) low-profile antenna is proposed; it is based on the discone antenna but with addition of a back cavity, a short-circuiting structure and a two-plate top structure in order to achieve both low-profile and wideband. It is simulated and prototyped. The test results show that the antenna has an omni-directional radiation pattern in the horizonta...
