While performing System Simulations, we need to characterize the non-linear behavior of an Amplifier accurately. ADS Connection Manager provides an easy way to build a non-linear behavioral model of an Amplifier DUT using Agilent Network Analyzers and ADS software.
Attached short note describes the simple way to doing measurement based non-linear modeling of an Off-The-Shelf Amplifier DUT.

Hope this will be of help to some of you.
Antenna Design Automation with Scripting and Parameterized EM Analysis
Date: February 7, 2013
Time: 10 AM PT/ 1 PM ET/ 6 PM UTC
Presented by: Agilent Technologies
Presenter: Dr. Raghu K. Settaluri, VP Engineering, Antennas for Communications (AFC)
Full-wave 3D EM software is an indispensable tool for designing RF antenna structures. However, complex array-based antennas can be cumbersome to set up and analyze in traditional EM software tools. Agilent EMPro has integrated Python based scripting that provides the user the ability to automate geometry creation, simulation and data analysis. This, combined with parameterization of key design variables can greatly accelerate the development process.
This webcast will illustrate the advantages of scripting and parameterization by considering the example of an MxN element Microstrip Phased Array patch antenna. A 3D model of the entire array with feed ports will be generated using scripting. Electronic beam steering of the antenna will be demonstrated by simply parameterizing the look angle without having to manually redefine the excitations at every antenna element. The array antenna model will also include excitations at any given frequency within the band at sum, azimuth-difference or elevation-difference modes, with or without the amplitude tapering, utilizing scripting and parameterization.
Who should attend:
Antenna designers will learn how scripting and parameterization in 3D EM simulators can accelerate the design process.
Webcast Title: Freescale’s Power Amplifier Design Methodology Innovations
Date: January 10, 2013
Time: 10 AM PT/ 1 PM ET/ 6 PM UTC
Presenter: Dr. Peter H. Aaen, RF Modeling and Measurement Technology Team, Freescale Semiconductor
Why this webcast is important:
This presentation provides an overview of a CAD-based design approach for high-power RF/microwave power transistors. These packaged transistors are typically constructed using several LDMOS die each with total gate peripheries up to 150 mm, metal-oxide-semiconductor (MOS) capacitors, arrays of bondwires, and are all placed within a metal-ceramic or plastic package.
To tackle the demanding design environment, a multi-technology, multiple design-kit approach has been used within Agilent’s Advanced Design System. These kits contain components that have accurate models, layout and schematic views, and are enabled to work with Momentum and/or Finite-Element-Method (FEM). This suite of design-kits standardizes the design process, enables design-re-use, and design rule check to improve design for manufacturability.
In this presentation, we will review aspects of the designer use-model where trade-offs between accuracy and simulation time must often be considered. For example, during the initial design, simple lumped component models may be used to study matching topologies. As the design progresses, design-kit components can be used for more accuracy and they support a straight-forward transition to full 3-D electromagnetic simulation with FEM. Additional libraries are later used to simulate the printed-circuit board to create high-efficiency Doherty power amplifiers.

Simulating Finite Ground and Defected Ground Structure in ADS using Momentum EM solver is very commonly asked question to me.
Here is one short note explaining the setup which can be easily used by designers.
Kindly let me know if you would like to obtain the ADS workspace in which these simulations are performed.

Agilent EEsof EDA announces its biggest annual event i.e. EEsof India User Group Meeting to be held in 3 Indian cities during the week of 3rd December.
On behalf of Agilent Technologies, I would like to invite you to present a technical paper in our upcoming EEsof India User Group Meeting (UGM). The tentative dates and locations for the event are as follows:
December 3, 2012 Bangalore
December 5, 2012 Hyderabad
December 7, 2012 Chennai
The EEsof UGM is an annual forum where users come together to share their ideas and success, discuss problems and interact with application consultants from Agilent Technologies.
Through such User Group Meetings, it is our sincere hope that together with elite RF/MW design-engineers like you, we can help build a strong high-frequency design community in India.
I hereby invite all interested customers to share their presentation ideas as per attached paper invite letter as soon as possible.
