Passive microwave components are electrical elements without gain or directionality, yet they perform a range of functions such as signal attenuation, filtering, dividing/combining and routing. Designed for every medium from RF boards to System in Packages (SiP) to integrated circuits (MMIC/RFIC), passives are ubiquitous and essential. Driven by complex...

A power divider is one of the most important passive circuits used in microwave and millimeter-wave applications. In 1960, Wilkinson proposed an N-way in-phase power divider. 1 He described a circularly symmetric power divider, which split a signal into N-equiphase and equiamplitude signals with an even or odd number...

The frequency spectrum is currently used for many applications and this resource is limited. There is also a growing demand for the use of higher frequencies, resulting from the demand from electronic warfare systems. Therefore, it is necessary to use the high band spectrum. The main advantages of working...

The last in a series of eight modernized Global Positioning System IIR (GPS IIR-M) satellites built by Lockheed Martin has been declared operational by the US Air Force for military and civilian navigation users around the globe. The satellite, known as GPS IIR-21(M), was launched successfully from Cape Canaveral...

TS2 Satellite Technologies is introducing new satellite link products to the international market. These types of telecommunication products are mainly used by the companies that execute contracts in the Middle East and Asia, as well as by soldiers that are stationed in Iraq and Afghanistan. “Purchased bands give us...

Northrop Grumman Corp. has received a contract modification from the US Department of Defense to further demonstrate a revolutionary advance in inertial navigation. The demonstration project makes use of traditional electro-optic (EO) cameras, atomic clocks, and advanced vision processing technologies to provide inertial navigation system (INS) updates to aircraft,...

The GSMA, the body representing the worldwide mobile communications industry, has signed a Memorandum of Understanding (MoU) to secure the deployment of a single, in-vehicle emergency call service, known as eCall, across Europe. eCall is an emergency call generated either manually by vehicle occupants or automatically via in-vehicle sensors...

The European Telecommunications Standards Institute (ETSI) has announced the creation of the ETSI Industry Specification Group for ‘Identity and access management for Networks and Services’ (ISG INS) to develop a common industry view on Identity Management (IdM) protocols and architectures, relating mainly to networks and services for the Internet...

The International Telecommunication Union (ITU), Inmarsat and Vizada SAS have reached an agreement to improve emergency communications for disaster preparedness and to coordinate relief activities in the aftermath of a disaster. Inmarsat and Vizada provide satellite-based solutions that are critical in supporting activities aimed at helping countries better respond...

C-MAC MicroTechnology and Linear Technology Corp. have formed a strategic partnership to provide the European, Canadian and Asian space markets with space qualified radiation hardened (rad-hard) monolithic devices and hybrid modules. This key partnership forms part of C-MAC’s strategy for growth within the space market following its accreditation to...
