Hi
I am working on a test fixture for an analog IC (low power, high frequency). What I have worked so far was a fixture with small pins on each line but I just saw another structure using a kind of fabric including lots of wires inside. They put this fabric between the part and the test board...
Dear all
i have a problem with tunning of a band pass cavity filter using in DVBT transmitter. it's a 6 pole uhf (Com-Tech CL6X30C) filter and i'm completely confused with this much tunning parameters, 6 pole positions, input/output ports positions, their angles, etc.
does anyone know any...
Hi
I'm looking for ATC 180R series design kit in the ATC web site but I can't find it there.
could anyone tell me where can i find it's ordering information and why it's not in their products?
i can find it in many other companies' products.
thanks
hi everybody
i'm really confused with designing of an ultra wideband (UHF full band) power combiner with branch line structure. i've found that branch line is better than wilkinson for wide band applications but the result of my simulations does not confirm it. it seems design of a branch line...
dear kodok128c
one kind of hybrid combiner is the branch line 90 deg coupler. it is simply a square like below:
port1 ====+===(lambda/4 and Z0*(2^0.5))===+====port2 (0deg)

ADS Help
hi
i have a power transmitter that i measured its S-parameter by a Network Analyzer of course with a Attenuator. i have the S file of the Attenuator and the S file of total system. how can i extract the single S-parameter of the first block (the transmitter)?
if anyone knows that...

ADS error
hi all
who knows the main reason of this error in ADS2005 on EM simulation
"invalid data encountered in the code"
some times i change type of ports from single to internal ,some times i clear cond layer in area out of the single port border,but some times i never can solve this...
