Antenna Magus is the first antenna design tool of its kind. Its huge searchable collection of antennas can be explored to find, design and export models of the designed antennas to CST MICROWAVE STUDIO.
Gallium nitride (GaN) is increasingly the choice of defense system amplifier designers because of its inherently higher power density than silicon or GaAs and broadband capability. However, customers want amplifiers that fully exploit GaN’s advantages in smaller and smaller packages.
In today’s world of highly complex Printed Circuit Board (PCB) designs, designing to meet electromagnetic compatibility (EMC) targets is a necessity. A step that is often times neglected during the early design stage is the design of a robust power delivery network (PDN).
Modern radio communication systems have to provide higher and higher data rates. As conventional methods like using more bandwidth or higher order modulation types are limited, new methods of using the transmission channel have to be used. Multiple antenna systems (Multiple Input, Multiple Output – MIMO) gives a significant enhancement to data rate and channel capacity. This application note gives an introduction to basic MIMO concepts and terminology and explains how MIMO is implemented in different radio communications standards.
"Protecting a mobile Radar unit from lightning strike is a very demanding task," commented Americo Dominicis, Selex-SI. "CST MWS, in particular its time domain simulation capabilities, helped us to understand the impact of various parameters on the specification of an LPS before running expensive, time-consuming tests."
High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) optimize UMTS for packet data services in downlink and uplink, respectively. Together, they are referred to as High Speed Packet Access (HSPA). Within 3GPP release 7 and 8, further improvements to HSPA have been specified in the context of HSPA+ or HSPA evolution. This application note introduces key features of HSPA+ and outlines the changes to the radio interface.
This application note describes ATSC Mobile DTV standard A/153, ATSC-M/H. This standard is completely implemented in the R&S®AEM100 ATSC-M/H Emission Multiplexer.
