This paper presents analysis and design of a dual band 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 dual band T-shaped sections. Simple design equations for the basic geometry are given. The designed dual band Wilkinson power divider str...

It is shown how to decorrelate the (prewhitened) power spectrum measured from a galaxy survey into a set of high resolution uncorrelated band-powers. The treatment includes nonlinearity, but not redshift distortions. Amongst the infinitely many possible decorrelation matrices, the square root of the Fisher matrix, or a scaled version thereof, offers a particularly good choice, in the sense that...

This paper presents the design and simulated performance of an ultra-low-power 4/5 frequency divider based on a CMOS ring oscillator. The divider operates over a 189% locking range (29MHz – 1GHz) for both division ratios, covering the MICS band and 433MHz and 915MHz ISM bands while consuming only 3.3 μW in MICS band. The wide locking range and low power consumption makes this very suitable for ...

a complete procedure for the design of w-band low noise amplifier in mmic technology is presented. the design is based on a simultaneously power and noise matched technique. for implementing the method, scalable bilateral transistor model parameters should be first extracted. the model is also used for transmission line utilized in the amplifier circuit. in the presented method, input/output ma...
