The "Guanella" 1:4 transmission line transformer can be used in different configurations, e.g. unbal-unbal. bal-unbal makes less sense according to the impedance values, but should work, too. The s3p files are however only specifying the unbal-bal configuration, as shown in the datasheet "Electrical Schematic". Additional parameters become effectiv

I'm trying to use the TCM2-33X+ transformer from mini circuits in an ADS simulation. Unfortunately their downloaded s parameters are 'not a valid touchstone format'.
Could someone show me how to convert the file (shown attached) into a valid format ADS can use for an s3p model?

In dchematic you must select the element s3p from the Data Items Palette. In the properties of this element you choose:
1. in "Parameter Entry Mode" - "Network Parameter filename"
2. in "File Name" - you point out a path to your file *.s3p
3. and take up "Edit"

I using a s3p as a center tap inductor simulate a VCO ,and the trans is work OK,while pss simulate is failed to oscillate,at this time ,I have to increase the width of MOS ,and it OK.why this happen, which one is more accuracy?
thank you in advance~

If you dont have a direct measure of s3p of balun it will be really difficult to solve this issue.
You don't have any info about amplitude and phase of differential signal generated by the input balun.
Roughly, if you are well matched, you just can divide by two the back-to-back insertion loss and deembed this value from the LNA meas.

I want to use a Touchstone file (name_file.s3p) in cadence for a PSS analysis.
I've insert a n3port in schematic, and in is properties:
name_file.s3p in S-Parameters data file
Touchstone in S-Parameters data format
After i've put the path (Include Path) and the name_file.s3sp (Stimulus File) in Setu

Hi. I am also facing the same problem. I am using simulink which only accepts s2p file for mixer. I have s3p and s1p files. I am not sure how to convert them into s2p file. any idea??????

*.s2p file is for 2-port data. There are *.s1p, *.s3p and *.s4p ... for different port number cases.
I suggest to open any existing *.s2p file and read the head of this file and you can easily find the definition of each column. Then you can study to write a s2p file by yourself

What I have done is the first option.
By definition S-par are valid in this configuration (the unused port terminated with 50 Ohm).
Then I used a software to merge the 3 s2p files into one s3p, simply removing the redundant measurements.
From s3p file you can calculate/simulate the balun insertion loss & umbalance.
If you use Agilent ADS, the

the issue here is , that band to band coupling will not be included , coz the s3p for the PCS and cell band only get the TX and RX and Antenna ports , and ignore the others
in most cases it is acceptable to use every s3p file to CEL in it is chain , and so on
i have done smehting linke this months ago ,
another solution , if u have time

I downloaded various S-Parameter .s3p files of 50 to 200 ohm baluns for 2.4Ghz operation from various vendors (i.e. TDK, Anaren, Johanson) and just want to verify that I get 200 ohm on the differential balanced ports. In looking inside the S-parameter files, they define port 1 as the unbalanced port and ports 2 and 3 as the balanced por

A lot of other balun at
I hope it can help.

I believe that you can't do this work in HFSS. But you can do it in Ansoft Designer by introducing a Data file with s3p representation.

My sistem s-parameters(I have it in *.s3p file) include connectors effect and I have connectors parameters in *.s2p file.
I need calculator to calculate my sistem s-parameters without connectors.
Maybe some program has this option but I don't know for that :(
