This article proposes a novel 8-channel Stepped Impedance Structure (SIS) RF coil for spinal cord imaging applications at 9.4 Tesla. The presented RF coil comprises eight stepped impedance structured ...

In cases where a multichannel component such as a phased-array antenna are characterized, precise control of the phase angle relationship between the channels is needed (Figure 1c). For digitally ...

Low-Earth Orbit satellites will be will need to have fast tracking from receivers as they move quickly across the sky. Receiving the internet with an affordable system is critical for the success of ...

Aimed at both commercial and military applications, Tahoe RF Semiconductor’s BeamDirect phased-array technology improves the bandwidth and sensitivity of phased-array radio systems and enables ...

Field-programmable gate arrays (FPGAs) are a critical component of both digital and hybrid phased array technology. Powering FPGAs for aerospace and defense applications comes with its own set of ...

The 31 P volume transmitter is a quadrature birdcage (21) driven with a two-channel (2 × ) 18-kW RF amplifiers (Analogic 8137, Boston Massachusetts). The 31 P body birdcage (inside bore) is a ...

If you watch old science fiction or military movies — or if you were alive back in the 1960s — you probably know the cliche for a radar antenna is a spinning dish. Although the very fir… ...
