Smartphones have become essential tools to many consumers—acting as a phone, camera, e-mail provider, schedule-keeper, and social-media enabler, among other things. Given that consumers are increasingly using their smartphones to take photos and videos, it is only natural that they should be enabled to easily share them with an audience via a bigger screen.
Missile defense systems must identify and respond to incoming threats in a short amount of time. Although they have reached great heights, US missile-defense efforts have thus far been contained to land. Recently, however, a US Army and Navy test demonstrated that Raytheon Co.’s Joint Land Attack/Cruise Missile Defense Elevated Netted Sensors (JLENS) can integrate with the defensive systems currently in the Navy’s inventory.
A number of standards have sprung up in the 57-to-64-GHz band, such as IEEE 802.15.3c, IEEE 802.11ad, and WirelessHD. No matter the standard, they all have one common goal: to speed the realization of integrated circuits (ICs) that can support large wireless data transfers at those millimeter-wave frequencies.
In the area of implanted medical devices, antenna-enabled biotelemetry is gaining attention for its potential to overcome the limitations of inductive biotelemetry. Such issues include low data rate, restricted communication range, and sensitivity to inter-coil misalignment.
A family of Ka-band GaAs chipsets has been developed by TriQuint Semiconductor for use in very-small-aperture-terminal (VSAT) satellite communications systems. The family includes a variable-gain amplifier, a 1-W power amplifier (PA), a subharmonic frequency upconverter, and a block frequency downconverter.
