Re: RF 2x1 power combiner
I realize there will be some loss.
Let me get more specific on what I want to do. I have two microstrip signals to combine, A and B. Both A and B have same frequency but are 180 degrees out of phase. I want to combine A and B onto one microstrip line...
RF 2x1 power combiner
Does anyone know of a power combiner type that can combine two signals with same frequency but different phase? Wilkinson's can do it but they have up to an additional 3dB loss for out of phase signals which I am trying to avoid. Now let me add some additional...
wilkinson divider
The units in ADS and HFSS are both set to um (including the HFSS dxf import screen). Also, the dielectric properties in HFSS are set to the same values in ADS. Any other suggestions?
Thanks for the reply
hfss wilkinson
I am modeling a 3dB wilkinson divider at 30 GHz. In ADS, the S parameters and performance is exactly what I would expect. I then export the layout in dxf and import it into HFSS. After adding all the geometries and ports to HFSS the model converges and solves. However, I have...
I am doing some simulations on simple microstrip structures. They are very small, 2 microns thick and about 6 microns wide. Also, they are 3mm long. I don't want to de-embed the solution at this point. Because they are so small with respect to my frequency, I have the solve inside the metal...
I have this same issue in some models I am working with. The simple answer is when the microstrip line thickness or width is less than 5 skin depths then skin depth loss should be included. In HFSS this means check the solve inside box for the respective line or ground plane. This really...
