Hello, Mr. Bhargava, thanks so much for the series training presentation! They provided great help for me. In this video, I have one question about the Xband band-pass filter. In the schematic design, you used MLSUBSTRATE2 and ML1CTL_C, ML2CTC_C, MLOPENSTUB etc. as tranmission line and coupling microstrip, at the same time added MTAPER and MSTEP. Since you just used two layers, I tried to just use MSUB for the two layers substrate setting, and used MLIN( transmission line), MCLIN( coulpling line), MLOC( open stub) together with MTAPER and MSTEP. But I got totally different S parameter simulation result from your design. The interesting point was when I transferred my schematic design into PCB layout and run RFPro in layout design, I could get the same simulation result as yours... So could you please do me a favor to let me know why you use MLSUBSTRATE2 for the substrate setting? What is the difference between MLSUBSTRATE2 and MSUB in case the PCB is only two layers? In the mmw band pass filter design example design in ADS, it only used the MSUB for setting substrate stackup. Thanks so much !!
Hi Mawuli, I didn't say IC package design. What I said was Multi Technology RF Module design where we will go over 2-3 MMIC chips inside a package for MCM kind of simulation set up in ADS Layout & RFPro.
@@BhargavaAnurag. Oh, I'm very sorry for quoting you wrongly sir. However, I like your videos so much. Therefore, whatever you have in stock for us, please bring them on board. Thank you
Does this apply to vendor PDKs too? If I have an UMS/OMMIC PDK and I want to do the circuit analysis with the active device model, e.g. the transistor, can we do it in a similar way as you showed in the case of a WPD? What it seems is that RFPro is a very powerful tool in terms of ease of analysis and data acquisition. Wonderful and highly informative tutorial.
Hi Deepayan, Yes, it should work with all the PDK components like the way I have shown for PD case. Infact Tutorail 47 will focus on taking a MMIC Amplifier example and I will demonstrate how to set it up for RFPro simulation and automatic EM-Circuit cosimulation etc
Dear Anuragji, my system takes more than 4 hours to run a amplifier RF pro simulation ADS 2020 update 2 licensed containing 1 amp and 16 lumped component (chosen) circuit view my system is 64 bit os windows with 64 GB RAM . why it is so could you please help in this regard
Hi, Looks like you need to setup proper simulation/mesh settings. It is difficult to look at your case on UA-cam and I would recommend you to call up local Keysight support person and he should be able to help you easily.
RFPro is fully integrated inside ADS and to use it you need either Momentum + FEM Super element or FEM element license. RFPro contains Momentum and FEM simulator licenses but no 3D drawing capability, it simulates whatever you assemble in ADS layout. EMPro is a separate standalone full 3D EM tool (think it like HFSS or CST software) containing FEM and FDTD simulator license with full 3D drawing and 3D model import capabilities. It can be used along with ADS to get designs from ADS to EMPro for analysis or to create custom 3D models and then send it to ADS for assembly and simulation purposes. Hope this helps.
Hi, I designed 3-4GHz and 6-8GHz RF BPF Filters in ADS (ie.,Hairpin, Couple line topology ) using Parametric Optimisation method available in layout ,the designed filters are meeting specifications in ADS traditional EM simulation, However, when I imported the same designed *.dxf file into ANSYS the Return loss get Varying at Bandedges (@100 MHz band) and Simultaneously IL The manufacturing filter results are same as ANSYS results, Want to know whether this variation not happen if I carry optimisation in ADS RF PRO? and which ADS EM Simulation is one to one comparable with ANSYS? Thanks, Praveen
Hi Praveen, Its difficult to say without seeing the graphs and you connect with me on LinkedIn to share some info. For your question on the comparison, using FEM in ADS would be same as HFSS...😊
@@BhargavaAnurag At this moment am using Momentum Microwave while Optimising the Filter, You suggesting to use FEM while optimisation also to get same performance in ANSYS (or)chose FEM method to compare with ANSYS results Regards, Praveen
@@praveenkumarbadam4029 to start with you could simply simulate the design using ADS FEM with the same condition as in HFSS and hope you would receive a pretty similar response. Once that is achieved you could decide where you want to use FEM for the optimization stage or only to be used in the final stages to fine-tune the response
Nice, but it would have been great, if you had explained how to add the resistor and give it a value, or if you have already done that in previous videos, then you should have mentioned which one and put its reference.
You can place R_Pad component from Lumped Components with Artwork library. Then you can define the footprint dimension as well as Resistor value etc. Hope that helps..

Great presentation, can't wait to see more videos especially on IC package design.... as you promised.

Its all good Mawuli. Just wanted to make sure you didn't get disappointed when the video comes out.

@@BhargavaAnurag Fantastic. Eagerly waiting for that...Thank you very much.
Very good lecture. I am inspired from your presentation. How can I get BPF design workspace? Do I need to design for myself?
Please design your own, it should be pretty simple to do...😊

Is RFpro comes by default with ADS? How it is different from EMpro?
RFPro is fully integrated inside ADS and to use it you need either Momentum + FEM Super element or FEM element license. RFPro contains Momentum and FEM simulator licenses but no 3D drawing capability, it simulates whatever you assemble in ADS layout.
EMPro is a separate standalone full 3D EM tool (think it like HFSS or CST software) containing FEM and FDTD simulator license with full 3D drawing and 3D model import capabilities.
