cavity filter calculating
Thanks phytech
I have done the model simulation in hfss, and try to optimize the parameters for this helical structure, but it took long time to run, any suggestion to figure out the mesh setting for helix? and another question, i wanna add capacitor at the open end...
helical filter coupling
thanks Phytech, cos this type filter needs 100w power connect after power amplifier. so the only solution is used helical cavity structure.
helical coil filter software
thanks vswr
i found your reply in other topic, which introduced two software to synthesis helical filter

**broken link removed**
first one is quite good, but the minimum bandwidth cannot be less than 1 MHz, and i use the...
helical filter design
im run the helical cavity bandpass filter for very narrow bandwidth filter 0.5MHz, and center frequency is 30 or 90 MHz, I have done lots research on this topic, but few materials can be found, and this technology is being used for very long time, but this type of filter...
wilkinson divider
when u convert dxf, hv u check the unit is the same(mil/mm), one more, hv u add substrate and ground in hfss cos when u convert to dxf it just like 2-D mask

Hi guys, could anyone share your experience on how to draw/simulate Radial Stub in HFSS. Because my design is a 3-D stucture (CPW-TO-Microstrip), and i know the RS could be easy simulate just by drag the icon in ADS. But in HFSS, I'm newbie. Many thanks.:D:D
