Kathiravan Krishnamurthi, Stephen Jurgiel, Ron Gatzke Eliminate LO Leakage and Reactive Loads in FET ZIF Modulators Base station transmitters based on passive field effect transistors (FETs) require zero IF modulators with high linearity and low carrier leakage. This article discusses the effect of reactive termination on the carrier leakage in these modulators. The reason for the loss of "zero" when suppressing the local oscillator signal is explained and simple diplexer schemes are proposed for significant suppression of the carrier in GSM transmitters operating at a frequency of 900 MHz.

Joe Gorin Elimination of large amplitude errors in the analysis of the microwave signal spectrum
Although modern spectrum analyzers have evolved to provide greater accuracy at high frequencies, their accuracy at microwave frequencies has generally not improved. Indeed, the accuracy requirements of analyzers by users are becoming increasingly difficult to meet with modern signals such as wideband digital modulation. The hardware and algorithms used in the new Agilent Technologies MXA Signal Analyzer help users achieve high accuracy without requiring a special type of input signal or external test signal.

Communication systems;
Vladimir Petrushak Advantages of using Telit GSM modems in security systems One of the main characteristics of any device, including a device that will be used in security systems, is its simplicity and reliability. This article is devoted to the advantages of using Telit GSM modems in security systems. Unlike GSM modem modules from Simcom and Wavecom firms, GSM modem modules from Telit have built-in flash memory and RAM. The presence of a built-in Python interpreter in these modules allows you to create devices without an external board with a microcontroller for collecting and processing information, which, in fact, simplifies the device, and at the same time increases its reliability.

Vitaly Shevchenko Mounting system for TO-220, TO-247 packages from Aavid Thermaloy To get the full functionality from discrete power components, it is important not only to turn them on correctly, but also to install them on a radiator. As you know, improper installation can lead to thermal and mechanical problems. The purpose of the article is to show an example of attaching a component to a radiator using innovative methods and its calculation of the radiator.
