Thanks for the clarification, base on the bandwith required in your design, you are absolutely correct. The frequency, size and cost would be a big factor if you choose to go with a passive design. I know that in a passive design, it will be hard to achieve the electrical characteristic that...
I agree if your power requirement is low. I'm a passive ferrite eng, my question for you is, are FET frequency limited? As far as passive device, especially ferrite product. There are 3 types of design. They are above resonance, resonance, and below resonance. For above resonance unit, you...
What's your electrical parameters?
Frequency is 9-10 Ghz, WR90
Isolation?
Insertion Loss?
V.S.W.R?
Operating Temp?
Power Handling?
Does it have a Pressurization Specs?
Type of Ferrite you are using at this frequency
Type of Magnet you are using to drive the Ferrite
Tohoma is correct. There a lot of parameters in HFSS you need to satisfy before HFSS is happy.
1. Specify all your ports
2. Select within your model the garnets or ferrite and specify it's characters.
3. Once you've done that you should be able to select magnetic bais. If you're running...
Answer to questions:
1. Google would be your friend.
2. Insertion Loss is base on what connectors if it's a coaxial unit, what type of garnets or ferrite in your design. Frequency and bandwith is also an important factor to consider.
3. S11 is the input, S22 is the output, S12 is insertion...
There should be an example provided in CST microwave. From my experience I find it faster getting a base design and plugging it to the VNA. It would take a couple more changes after and the design is complete.
Simple answer is no, Fet cannot handle as much power as an RF Isolator can. Some may know but others may not. A circulator has 3 ports which normally consist Port 1 is the input, Port 2 as an output and Port 3 is loaded with a 50 ohm load. The load is there in case there are feedback from...
