A sound amplification technique from SLS Loudspeakers (Springfield, MO) promises to reduce the size and cost of high-power, professional quality speakers. The approach, dubbed Evenstar, uses a pair of ...

“Photon Design's next-generation, EPIPPROP simulator, will offer the flexibility to split waveguides, simulating this process ...

A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

OpenLight and Tower Semiconductor have announced a successful demonstration of a 400G/lane modulator on Tower's silicon photonics platform, PH18DA, which achieves over a 3.5dB extinction ratio using ...

Innovation paves the way for a high-volume, silicon photonics 400G/lane platform to meet next-generation 3.2T optical communication architectures for datacom and AI applications. The integrated ...

Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they need to have the same color — or frequency — and bandwidth. Changing a photon’s ...

CML Microcircuits unveiled a new I/Q modulator in its family of RF integrated circuits. The CMX993 is a highly integrated, general-purpose RF quadrature modulator that operates between 100 MHz to 1 ...

Unless you design EDGE or 3G/UMTS cell phone handsets, you may not have heard of polar modulation. As you know, there are only a few basic types of modulation, but they have been used in a variety of ...

In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. This paper ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...
