So, I understand that i must choose a technology which thickness and height are obtained, in addition, this technology should work at 33 GHz.
Would you please how can I choose a technology?
And where can I find various technologies?
Dear volker,
Thanks for your great guide, but i have no sense of standard line parameters, such as FR4 and thickness.
Would you please help me how to select line parameters, consider that i dont have any choosen technology.
Thanks a lot.
Hi,
I want to implement a CPW power divider in ADS which can work at 33 GHz.
According to the 1st and 2nd attached images, using LineCalc tool in ADS, I have designed the CPWs for power divider for 50 and 70.7 Ohm characteristic impedance.
According to the 3nd image, the length and width of CPWs...
Dear BigBoss, thanks for your guidance.
I have other questions please:
1- Are there any ready to use blocks in ADS for waveguide to microstrip (WG to MS), microstrip to waveguide (MS to WG), waveguide divider, waveguide combiner, isolator, and coupler, which I can use them in simulation?
2- How...
Dear all,
Hi.
I have a circuit and want to implement it in Advanced Design System (ADS) software. I dont want to design it, instead I want to use the parts (ex. waveguide to microstrip (WG to MS), microstrip to waveguide (MS to WG), waveguide divider, waveguide combiner, isolator, and coupler)...
I don't have ViVa and Waveviewer, although i think no changes will be on results!
I looked for log files and find nothing. As I mentioned, I have used HSPICE version 2010 and Cadence version 6.14.

Yes, as I mentioned in my first post, the circuit has an active feedback...
I did as you suggested and results are as follows:
Spectre:
HSPICE:
No changes in results! :roll:
I mean, can i accept these results and report them, although I think that simulation conditions are standard and P1dB should be less than IIP3 by about 10 dBm! But, here IIP3 is less than P1dB...
I am working on a LNA which has an active feedback. P-1dB and IIP3 are simulated using Spectre and results are as follows:
P-1dB:
IIP3:
In addition, these parameters are simulated using HSPICE and results are as follows:
I have two questions:
1) simulation conditions for both Spectre and...
Dear dick_freebird,
Thanks for the response.
Terminal 4 is the name of BULK terminal in subcircuit.
Terminal 4 of the subcircuit is named 27 in the netlist. BULK of all of the inductors are connected to the node 27.
Yes, intended end of resistors are float.
I think I have to use another (or new)...
Dear dick_freebird,
Thanks for your attention.
I saw the extracted netlist of the layout. Inductors are known like follow:
.SUBCKT spiral_std$$209091628 PLUS MINUS 4
** N=5802 EP=3 IP=0 FDC=1
X0 PLUS MINUS 4 spiral_std w=1.5e-05 nr=4 rad=3e-05 lay=8 $X=-103500 $Y=-46055 $D=50
.ENDS
but the...
Dear all.
I am using 0.13 um PDK in cadence. In my circuit, I have 8 spiral inductors, which bulks are connected to the ground by means of a resistor. For more detail please refer to my post:
After doing LVS using Calibre, I have encountered an error, which says that bulk of spiral inductors...
