Hi everyone,
I have following problem and I believe someone of you will help me.
My task is to calculate resonant frequency of rectangular waveguide (operating with TE10 mode) utilizing FDFD method.
I know that problem must be formulated as a eiegen value problem, where eigen values are...
Hello everybody,
I want to buy software for designing antenna and research EMC problem. Can you share with me your experience with EM simualtors in this subject. I am thinking about FEKO and HFSS but i really dont know which one to chose.
I will be grateful for any advices.
Best regards
Lukasz
I do not have the evaluation board. I have just draw circuit from reference data sheet and start simulating. When I perform small signal stability test (K, B1) I saw that in band 0.1 - 5.1 GHz the amplifier is not stable, in my opinion it should be stable but I am newbie in power amplifiers. So...
I have added series and parallel resistor with the input. In effect stability circles in input/output was moved out of smith chart but gain, efficiency degrade. I really don t know what to think about reference datasheet **broken link removed** because it should work.

Lukas
Hi,
I'm looking for some help in designing power amplifier for wimax. Precisely my question is about stability. Because I have to use Nitronex transistor NPT3015 I was utilizing following datasheet **broken link removed** . When I perform small signal stability test (K, B1) I saw that in band...
