This application note illustrates how CST MICROWAVE STUDIO (R), Antenna Magus and Optenni Lab can be used in combination to improve an existing GSM tracking device application. The requirement was to. replace an existing "off-the-shelf" antenna on a GSM tracking device with an embedded, integrated...

...will attempt to build a. bridge toward better understanding of the differential VCO by. describing a design covering 910-980 MHz which is appropriate. for use in GSM handsets. This design will also demonstrate how. the SMV1493-079 varactor diode, an essential element in this. VCO, may be used...

This application report describes how to design power supply for a Global System for Mobile Communications (GSM)/ General Packet Radio Service (GPRS) module....

Introduction to Global System for Mobile Communication (GSM): Physical Channels, Logical Channels, Network, and Operation. Through a thorough description of key functional sections of a GSM network and how they communicate with each other, you will learn how and why GSM is evolving into 3rd...

Gyricon, the reusable electronic paper developed by Xerox, is nearly thin as a sheet of plastic laminate. First developed in the early 1970s, Gyricon (a Greek term meaning rotating image) is a reusable form of e-paper (electronic paper) designed at Xerox's famed PARC (Palo Alto Research Center)....

Many of today's handset cellular telephones are multifunctional,. multiband units. They are complex RF systems with frequency. plans requiring multiple RF sources. To accomplish this, the. number of VCOs can be increased, however this is expensive and. requires more PCB area. This approach strongly...
