Hi all,
I'm designing PCB and I have 2 SMA connectors - in, out. Unfortunately, I have to route 3 signals for LEDs under (bottom layer) the coplanar waveguide which providing path to the RF signal (top layer).
Do you have any tips to do it most "correctly"?. Should the LEDs signal be placed...
mis-matching network should simulate, that the device A does not have matched output.
There will not be problem with some lossy or that the circuit won't be reciprocal.
Do you have any ideas? I was thinking about band pass filter - input impedance matched, output will be mis-matched.
Hi guys,
does anyone know, how to design filtr with specific output impdeance? I've done some research on internet and there are calculators, tips etc. how to design filtr with 50 ohms of input and output impedance. But I need filter with complex output impedance (viz. attachement).
Could...
Correct me If I'm wrong, but if I have input 50 ohms, then LC network (using for changing the impedance), and then I connect antenna with 50 ohms, it will change both S11 and S22 the same way. What I do is actually mismatching the device A port, so connected antenna is will not be perfectly...
Hi,
I need help with this "problem".
I have device A, which has 50 ohm output port (900 MHz). I also have antenna with 50 ohm input. So There is no problem.
Now, I wanna make a new device "blackbox". Input of the blackbox should be matched to the 50 ohms (so there is no problem with reflected...
