    Agilent to Acquire Eagleware-Elanix

    @gilent to Acquire Eagleware-Elanix it's not a good news, genesys has many professinal article or application,that will be very helpful for beginer.

    may i confirm the EM tools used in MWO is 2.5 D MOM?

    just as it can handle plane multilayers and vias, it is called 2.5D, but not 2D.

    How to maintain NF? reducing the signal power...

    using parallel gate-drain negative-feedback also reduce the gain and improve the NF.

    Resources about heat-sink design and thermal theory

    heat sink design software here is another application note"mounting considerations for power semiconductors"

    Which EDA software is better, Eagleware or ADS?

    Eagleware is famouse for its synthsis functions, its model is simple. ADS has very large, complex model and function,it can design any circuits,but it is costly.

    What is the best 3D Field solver tools

    solving radiation problem 3d fem In general, It is well known ansofthfss and cstmws are two great 3D sover. cstmws is more easy to build model.

    Via-In-Pad or Via-Next-To-Pad - which is best?

    the inductance is related to the track width and length, vias diameter and depth. the good method is using EDA software to design.

    How to calculate the resistance and inductance of vias

    how to calculate multilayer inductance DC-50MHz,the vias resistence and inductance can be ignored, They are very small ,less than 1OHm or 1nH.

    What is better Micorwave Office 2002 or Genesys 8.11?

    genesys has good synthsis functions, for example:PLL,filter. In this point other software cannot match and replace it.

    Noise figure of a 10 dB spliter (or x-dB splitter)

    coupleur noise figure when the input signal noise power is very small, the noise make up of half AM noise and half FM noise,the AM part can be attenuatted,FM can not be. thus the attenuation of signal and noise is diffrent. in addition, when the input signal noise power is the minimal...

    Noise figure of a 10 dB spliter (or x-dB splitter)

    splitter noise figure In fact,the transport and coupled port has the same noise floor, the different is the signal amplifude decrease 10dB in the coupled port, and when using noise figue instrument measure the coupled port noise, it shows the noise figue 10dB.
