This document summarizes an IDS Specialist Project to standardize the spurious analysis process. It includes a project schedule, objectives, and details each step of the process including visualizing the problem, committing resources, prioritizing solutions, characterizing the current process, improving by selecting Spectrasys software, and achieving the goal of a standard template. Spectrasys was chosen over other tools like Matlab, ADS, and Excel as it provides an easy to use interface, truncates low level signals to reduce simulation time, and can import files from other tools. An improved standardized process using Spectrasys is expected to save significant time and money across projects.

• Current process for flow chart

Start writing

Run the
simulation,
graph it
And get a data
Time consuming, complicated, and
High opportunity for clerical error

9. 9
Characterize
• Current State:
 Couple of programs are being used to do spurious analysis such as
Matlab, Excel, spurious charts, ADS and Spectrasys.
 Therefore there is no single standard process to do spurious analysis
which led the following UDEs.
– Matlab is good for accuracy but its not as easy to use
Each problem requires new or modified code.
It requires also programming knowledge which every one
does not have.
– ADS could be used spurious analysis but it does not truncate the
Lowe level spurious signals, continuous to process insignificant
low level signals this results considerable longer simulation time
and more memory requirements
– Excel and spurious charts may be used however prone to error
due to manual interaction requirement.

Characterize
• Root Causes
 5 whys to determine the root causes
Engineer came up
a process to do spurious
analysis for every
new designReviewers are required to
use a new tool for
every new design analysis
Every engineer tries
to analyze
Spurious His/her own way
Analysis or
synthesis is too costly
There is no single

Do spurious analysis
Analysis or

As you can see the chart Spectrasys has more capability
then all other tools

Spectrasys
 Why Spectrasys over ADS
 Spectrasys has a capability of truncating Lowe level spurious
signals
 ADS does not have this capability and continuous to process
insignificant low level signals this results considerable longer
simulation time and more memory requirements
 This also limits maximum number of mixer conversions which can
be handled
 Spectrasys traces the origin of the spurious signals by simply
placing the mouse over the graphical spectra this is represented
as M*RF+N*LO
 Spectrasys interfaces with a number of tools including ADS
 Spectrasys more easily performs system level analysis as the roots
are already written and usable with clickable button
 ADS purchased Spectrasys to simplify spectral analysis

Improve
• Management and Control Systems
– What will make the implementation permanent?
Incorporate as requirement for PDR/CDR process
– Documentation and/or training requirements
Incorporate training through LMS or vender seminar session
lunch and learning
– How do I know I’ve actually improved anything?
Its when every one starts using spectrasy for spurious
analysis
– What are the metrics showing improvement?
Its when you can not log in easily and need more license
every time you want use spectrasys

14. 14
Improve
• Solution Chosen:
 To use Spectrasys as a single standard tool when performing spurious
analysis
• Improvements made
 time and money saved
 Only one single standard tool needs to be learned to do
spurious
 One single analysis could be done both spurious and
system analysis
 A file from ADS or HFSS could be imported in to Spectrasys and
do all the analysis you need.

Start spectrasys
Accept the default window
and give name by right clicking
the schematic
Type the name of the parts you
Want in the Filter By window
Which is on you right hand
Corner and place them in the
workspace
Connect the all the parts together
And double click to change
The parameters
Analyze by right clicking the design
And then selecting add and then
Selecting Analysis and then selecting
The type of analysis you want
Adding a graph right click the
Design, then select add, then
Select add graph
Complete the
analysis

16. 16
Process
• Start the Spectrasys
• Select a default from the template window and click okay
• Give a name called mixer by right clicking the schematic.
• Type continuous wave (CW) , Mixer, Power oscillator, Isolator, RF amplifier, Filter and out put port separately a place
called Filter By which is on your right hand corner and then place each part on the workspace.
• Connect all the parts together and then double click the part to change its parameters
• This is how it should look like

Pwr=0dBm
F=60MHz
SRC_RF
Pwr=15dBm
F=580MHz

17. 17
Process
• Add another schematic called filter by right clicking Design then select add, then select design, then select add
schematic
• Type Input port, RF amplifier, Filter and Output port separately in the place called Filter By and then place them on
the new schematic.
• Then this is how it should look like
ZO=50Ω
Port_2
ZO=50Ω
Port_1
Fhi=550MHz
Flo=490MHz
N=7
IL=1dB
FL1
NF=3dB
G=12dB

Process
• To analysis the filter, right click the design select add, then select analysis, then select add linear analysis, then a
window pops up choose start and stop frequency, type of sweep and number of points then click Calculate now and it
generates a data for you.
• To analysis the mixer, right click the design select add then select analysis then select add RF System analysis then a
window pops up click paths then click add all paths from all sources click options and type -80dBm in the level below
then go back to the general tap and click Calculate now and it then generates data.
• To add a graph, right click the design, then select add, then select add graph, a window pops up then click add button,
then select Spectrum from select type of series then click the linear data and select “S” which is “S21” by default
click okay, click add again then select Spectrum from the select type of series then click System Data and select
POUT which is output power of the mixer then click more measurements then go down and click Pnode which is the
power node then select Pout then click okay then click okay again then you get the graph you see below
