Inductor Synthesis for III-V Technologies

Published on 2, Jun

Inspired by our popular RFIC Inductor Toolkit for Silicon technologies, several ADS users have been asking for an MMIC version that addresses III-V technologies. This new MMIC Inductor Toolkit is ready for release now, with special early bird discounts: Inductor Synthesis for III-V Technologies

ADS: Using Equations and User Defined Functions in ADS

Published on 5, Apr

In this appnote, we will look at different ways of using equations in ADS: simple equations “on the fly” in the ADS data display and user defined functions that you can use in data display or optimization for target definitions. We will also discuss the re-use of custom equations/functions. All these concepts are shown with […]

ADS: Miniaturized Bandpass Filter (AEL layout example)

Published on 30, Mar

In this application note, AEL programming is applied to create a fully scalable layout of to the miniaturized band pass filter by Sheng Zhang et al, published in Microwave Journal March 2017 Miniaturized Bandpass Filter Using Quarter SIW Resonator With Elliptic Defected Structure This fully parametric layout cell can then be used in ADS for […]

ADS: Using layout parameters in Momentum EM simulations

Published on 13, Nov

In this application note, we will look at two different ways of using layout parameters for Momentum EM simulations: Use built-in parameters in layout created from standard circuit elements (microstrip line etc.) Parameterize manually drawn layout from rectangles/polygons We will discuss the use EM results of parameterized blocks in a schematic, with emSetup/emModel views. A […]

Microwave Office: PCB antenna simulation 868MHz

Published on 23, Jan

In part one of this application note we had discussed basic design concepts and simulation methods for “printed” PCB antennas. Now in this second part, we will discuss advanced topics: Co-simulation of antenna and SMD matching components for electrically small antennas Using the Analyst 3D FEM solver to include the effect of finite PCB size, […]

Microwave Office: PCB antenna simulation 2.4GHz/5.6GHz

Published on 16, Jan

This document describes the design and simulation of simple PCB antennas for 2.4GHz and 5.6GHz with Microwave Office and the Axiem EM simulator. The first example shows a 2.4GHz single band antenna. The second example then shows a dual band version for 2.4GHz and 5.6GHz. Finally, we will investigate the sensitivity to PCB material tolerances. […]
