A high performance dual ultra-wideband (UWB) bandpass filter with 5 to 6 GHz rejection band is proposed. The multiple L-shaped SIR resonators are incorporated with multiple-mode resonator (MMR) to provide wide transmission band and inhibit the signals ranged from 5- to 6-GHz.
This paper presents a mobile synchronization approach that could afford an inaccurate and inexpensive crystal . The carrier frequency synchronization is achieved by adjusting the fractional-N PLL while the time base synchronization is obtained by introducing simple physical layer algorithms and existing hardware.
This paper discusses a new pad scalability feature added to selected Global Models contained in Modelithics CLR Library[1,2]. The correlation between high frequency measured data and simulated performance, as well as interesting features such as arbitrary pad shape simulation, are also explored.
In this paper, error items of the demodulator in the feedback path are analyzed and the compensating algorithm is derived. Also the simulation is completed to validate the closed-form algorithm in the numerical way.
