The complexity of current 4G/5G phones comes from the need to cover multiple bands. Modern modems like the ones used in mobile phones are compatible with multiple transmission bands, including 3G, 4G LTE, Wi-Fi, and Bluetooth. The radio frequency front-end (RFFE) section of cellphone includes components like antennas, LNAs, filters, …

The RF design consists of passive as well as active components. The inductors, capacitors, and resistors are one of the three passive elements that are the foundations of all electronics. The discrete and passive components are an integral part of the design; from front-end antenna matching to tight-tolerance mixers, oscillators, …

One of the most common functions in all electronic circuitry is switching. Switching has a wide range of uses. Engineers in industries ranging from telecommunications to military/aerospace need high-performance RF/microwave switching as part of their test setups. An RF switch or microwave switch is a device to route high frequency …

The terahertz (THz) frequency band is a fascinating and relatively unexplored part of the larger electromagnetic spectrum (EMS). The terahertz frequency range, lying between electronics and optics (300 to 3000 gigahertz frequencies), can be disruptive force in sectors as diverse as from medical imaging, biological research, pharmaceutical monitoring, manufacturing and quality …

Stealth technology has proven to be one of the effective approaches to enhance the survivability of Aircrafts. Aircraft/helicopter designers are making them stealthier by reducing their signatures; viz. visual, aural, infrared (IR), and RADAR cross section. Advancements in stealth technologies, as demonstrated by the very low RCS of stealth aircraft …

Electronic warfare provide means to counter adversary’s radar and communication systems while protecting one’s own systems through Electronic Attack (EA), Electronic Protection (EP) and Electronic Support (ES). Jamming systems still rely on classified databases of known emitter signals. As radars emit energy, an onboard receiver characterises the incoming signal and and …

RADAR offers special advantages with respect to other types of sensors including all-day, all-weather operations, long detection distance and, depending on the frequency used, penetration. Moreover, radar can often be carried by a number of platforms, spanning from classic naval and airborne to more recent space-borne, UAVs, such as drones, …

Weapon Locating Radars (WLR) are primarily used to detect and locate enemy Artillery units by tracking the trajectory of incoming rounds. They can also provide fire correction of friendly artillery units. WLRs usually can also track mortar shells and unguided rockets. Some WLRs also have limited missile tracking and Air …
