I wanna design a LC filter by myself. the center fre is 600MHz and BW is 40MHz. I use ansoft designer to sythesis the filter but I find the C is very small (about 0.3pf) which is not easy to realize. how can i transform the small C to some bigger??
I am very appreciated if someone give me the...
rf choke for 100mhz
i design a rf circuit working at 100 mhz. there is a rfc in the circuit to choke the ac signal and it is about 40µh ,but i cannt find such a big inductance working at 100mhz. who can give me some advice? thanks a lot!!
Re: how can I combine HFSS with Designer to design wg filter
but I can not find it is needed to be linscenced.

who can tell me the reason?
I saw some ppt of Ansoft which talk about designing waveguied iris filter using HFSS and Designer. In the ppt, We can use HFSS to simulate the basic module of the irise filter and add it in the Designer as a subcircuit . At last , using the optimetric of Designer , we can get the final physical...
Sonnet is a 2.5D simulator and CST is a 3D simulator , just like the Ansoft designer and HFSS. Sonnet is used to simulate the planar circuit such as microstrip , CPW, strpline circuit etc. and I think it is very accurate and fast cause I have used it for a long time .
I wanna research on DDC or DUC and some related technology such AGC DDS etc. in SDR. but I donnt know whether these tech mature and it is necessary to do it.
my job is rf and microwave system design, but I find it is very boring . so I wanna change my research field in SDR . but I donnt know how about it and if i should give up my job. who can give me some advice? thanks!!!
when you change the structure of you design , it is necessary to tuning the filter in the simulator. the optim in HFSS is very powerful but it is very time-comsuing.
I find a new method to design every resonator-coupling filter including iris waveguide filter . it is very efficient and...
