Spotlight On Satellite Technology/Space-Qualified
Are You Space-Qualified?

The industry is experiencing an explosion in space-related applications, such as satellite communications, lunar travel, deep-space satellite exploration, space stations, weather tracking, global mapping, and global positioning technology. Is your company positioned for space exploration?

A Classic LNA Design Challenge: Meeting The Satellite Digital Audio Radio Service (SDARS) LNA Specification

This article focuses on a high-volume application: the multi-stage LNA associated with the SDARS radio capability included with millions of new cars every year. It requires a cascade of multiple high-performance amplifiers and filters to meet a very difficult set of requirements.

What The Heck Is An OCXO Oscillator?

OCXO stands for oven-controlled crystal (Xtal) oscillator. OCXOs are the top-performing type of quartz crystal oscillators at the expense of power. Other types of quartz crystal oscillators include TCXO, VCXO, and just plain XOs.

Industry Insights
Implementation Margin Of A Satellite Communication System

To find the implementation margin of a satellite communication system, an EbNo generator can be used to carry out an IF loopback test of the modem to find bit error rate (BER) values at different Eb/No ratios. A plot of these values can be compared with the theoretical curve for the digital modulation scheme.

In Situ Calibration Utilizing The R&S ZN-Z3x Inline Calibration Units

This app note covers a new calibration subsystem consisting of ICUs designed for in situ use. This method adds versatility, convenience, and accuracy to the VNA-based measurement system, as it allows calibration to be refreshed at any time without manually disconnecting the DUT from the test system.
