In this paper the authors investigate and present a patent pending novel micro-strip coupler structure that exhibits very low RF insertion loss (high coupling) while insuring high electrical isolation (>10kV) between the wireless Network Interface Card (NIC) RF connection and the external antenna.

Fiber Optic Delay Line systems (FODL) are used in test and development laboratories to eliminate outdoor range testing of radio and radar systems. Outdoor range testing is costly, complex, and time-consuming.

The True Balanced/Differential technique uses two sources to create actual differential and common-mode stimuli, hence the shortened name true-balance. This white paper offers guidance to signal integrity designers on the differences between these approaches and which one may best fit their need.

Skyworks offers RF microwave products for defense and homeland security systems, including radio communications, radars, electronic surveillance, electronic countermeasures, and more.

In addition to our standard consumer off-the-shelf (COTS) product offering, diode product screenings equivalent to up to JANS level of MIL-PRF-19500 and Class K of MIL-PRF-38534 are available.

The scope of the subject “radar” has expanded in the recent years in terms of its technical evolution and spreading of applications. This application note along with its corresponding white paper 1MA207 show how to use the R&S radar product portfolio to tackle test and measurement tasks in modern radar technology. Target groups are students who want to become familiar with radar issues as well as radar professionals who want to solve certain test and measurement tasks

Near Field Communication (NFC) is a new short-range, standards-based wireless connectivity technology, that uses magnetic field induction to enable communication between electronic devices in close proximity. Based on RFID technology, NFC provides a medium for the identification protocols that validate secure data transfer. NFC enables users to perform intuitive, safe, contactless transactions, access digital content and connect elec­tronic devices simply by touching or bringing devices into close proximity. This White Paper gives an overview of NFC uses, NFC technology and signals, RF measurements on NFC units and shows some examples of measurement results using R&S test instruments and special R&S NFC software tools.

Multiple input multiple output (MIMO) technology is an integral part of 3GPP E-UTRA long term evolution (LTE). As part of MIMO, beamforming is also used in LTE. This white paper discusses the basics of beamforming and explains the eight MIMO transmission modes in LTE Release 9.

This white paper provides a brief technology introduction on the 802.11ac amendment to the successful 802.11-2007 standard. 802.11ac provides mechanisms to increase throughput and user experience of existing WLAN and will build on 802.11n-2009.

The LTE technology as specified within 3GPP Release 8 was first commercially deployed by end 2009. Since then the number of operators implementing the technology is strongly increasing around the globe. LTE has become the fastest developing mobile system technology. The same way GSM and WCDMA have been enhanced with additional features over time, LTE is continuously worked on. Initial enhancements have been included in 3GPP Release 9 and are described in this white paper.
