I have a question here hope somebody can answer it.
In EM software (e.g. HFSS), the Eigenmode solver can simulate the resonant frequencies of any random closing structures.
So why those frequencies are called "Eigenmode" from the simulator? Does it relate to the "Eigen value" or "Eigen...
FvM, thanks for the reply.
Linear Polarized mode, you mean for example TEm0 mode? Yes, I understand for those modes, H-filed only has X and Z vector (assume XZ plane is the so-called H-plane)
However, We know H-plane Filter/discontinuity also supports other TEmn mode, e.g. TE11 mode, which...
Understand H-plane filter has the same "B" dimension, why does it called "H-plane", relating to Magnetic field not changing on the plane?
H-plane waveguide structure only support TEmn mode, which has Ex, Ey, Hx, Hy, Hz vector, correct? So the magnetic vectors are on all the directions....
So...
I am not a planar guy but the basics are always the same.
The structure looks to me like a T network, two series inductors and a shunt capacitor between them.
Spiral inductor, you can find equations everywhere online to calculate an approximate L
Capacitor, you can use the parallel-plate...
Pseudo-HPF? You mean actually a BPF but used as HPF?
Normally Coupling Matrix is used to "describe" a BPF. The matrix tells the resonator offsets and coupling connection between resonators. Mathematircally, the coupling matrix elements are related to its corresponding lowpass prototype...
Hi,
I am trying to design a 7-order extracted pole filter (1 transmission zero on high side). Is there any good synthesis tool to get something e.g coupling matrix?
Thanks.
Lee
in his case, it cannot.
His narrowest BW is around 2%, and filter order less than 5, which is not possible to have 10db level IL, based on current regular dielectric material.
I am afraid I cannot agree with upstairs....dielectric/cond. loss won't make a 10dB IL.
R u making Microstrip filters with SMA connectors? Seems like the biggest suspect is your input/output coupling. Make sure you did a good job on soldering at the connectors.
