In the coming years, data-rates for internet consumers will need to increase dramatically to be able to support connectivity anywhere, any time, and for any user. The current terrestrial 3G and 4G telecom networks with one-way and two-way satellite backhaul networks are implemented to cover the demand, but the available data-rate is not enough, especially in the satellite segment. This white paper discusses the existing satellite architectures, the future of their technical evolution towards greater bandwidth, and the particular solution of wideband operation as per Annex M, introduced in the DVB-S2X2 standard.
Tools are now available from Anritsu to help technicians determine the precise location of external PIM. Using the Anritsu PIM Hunter™ probe in conjunction with a spectrum analyzer, technicians can use traditional interference hunting techniques to locate external PIM sources in the field. This white paper describes the test process as well as provides important guidelines to consider while testing.
As 5G technologies are developed to increase wireless communication data rates by a factor of 100, the design specifications of radio frequency (RF) electronics have become much more rigorous, especially for millimeter-wave (mm-wave) applications. As an alternate solution to traditional low radiation and low gain antennas, Dielectric Resonator Antennas (DRAs) operate with less conduction losses and feature high radiation efficiency when excited properly for mm-wave frequencies and beyond. This white paper presents additional DRA characteristics, and the advantages of using them for 5G technology development.
As new power amplifier (PA) technologies are released, the latest being GaN technology, an amplifier’s behavior must be thoroughly tested and evaluated to ensure the highest performance under the stress of high power pulsing signals. Since a pulsed RF signal has a time domain nature, the best way to observe the performance of an amplifier is through time domain signal analysis. This article explains how to characterize the behaviors of pulsed RF power amplifiers in radar systems with a peak power meter.
In order to generate noise power ratio stimulus signals and to measure the resulting noise power ratio of a device under test (DUT), Rohde & Schwarz offers the Noise Power Ratio (NPR) as an add-on tool for WinIQSIM / WinIQSIM2™ software. This NPR measurement technique drastically reduces measurement time compared to classic gain wobbling, and is able to characterize the linearity of a wideband amplifier over a custom frequency range. This application note provides an overview of the software, its features, hardware and software requirements, installation, parameters, and more.
The Standard Gain Horn Antennas are designed specifically for utilization in emissions and immunity testing over the frequency range of 1 to 40 GHz. Each antenna is linearly polarized and has medium gain, low VSWR, and a constant antenna factor.
The DCB is a DC voltage block. This will allow you to block the DC voltage from going where you don't want it to go while allowing GPS Signal to pass through
CPI’s Beverly Microwave Division presents the VSC3645 GaN 4.2 kW pulsed solid state power amplifier module operating in the C-band (5.2 – 5.9 GHz).
