    Dielectric resonator Filter at 915MHz

    I have a very narrow band filter at 915MHz with a 26MHz band pass. Its rejection at 930MHz is more than 30dB!!!!. I think it is a dielectric resonator filter but I am not sure about it. The photo is attached. Please help me to find the type of this filter and the part number of resonator. Best...

    how to verify gama of mos transistor

    If u have software(like CADENCE or HSPICE) u can simulate it in a suitable DC bias but if u want do it in a discrete circuits, ur result will be wrong!

    beginner! question about testbench

    If your use Active_VHDL there is an icon called "wave_form". after double click, appear a window in right and all signals and variable in left. you can select them to display. Good Luck moghtada
