Experiments Begin For Communications Testbed

Thu, 09 May 2013 13:35:00 +0000

In addition to raising its understanding of software-defined-radio (SDR) technologies and how they may aid NASA’s communications, this technology is expected to provide both cost savings and efficiency.

Manpack Radio Calls On-Orbit MUOS Satellite

Thu, 09 May 2013 13:23:00 +0000

Using the same cell-phone technology that powers commercial smartphones, the PRC-155 Manpack has demonstrated the capability to communicate with the MUOS space-ground network.

Smartphones Prove Their Worth As Satellites

Thu, 09 May 2013 13:17:00 +0000

Three smartphones, which are destined to become low-cost satellites, rode to space last month on the maiden flight of Orbital Science Corp.’s Antares rocket. It was launched from NASA’s Wallops Island Flight Facility in Virginia.

GaN-On-Diamond Breakthrough Promises To Shrink Transistors

Thu, 09 May 2013 13:08:00 +0000

The feasibility of GaN-on-diamond HEMT devices has been proven with the successful transfer of a semiconductor epitaxial overlay onto a synthetic diamond substrate.

The Cobra Judy Replacement program is tasked with delivering a high-performing ship-board radar capability for use by the US Navy, Air Force, and the nation.

TES Detecting Device Cuts Noise Equivalent Power

Wed, 01 May 2013 14:16:00 +0000

This group of researchers found ways to compensate for the combined heating effect arising from the fact that the thermal relaxation time of the TES film is much longer than the period of the RF current.

Modular SoC Design Integrates RF Transceiver In 32-nm Process

Mon, 29 Apr 2013 13:54:00 +0000

This system on a chip (SoC) integrates diverse digital, analog, and RF blocks on a single die, allowing the RF transceiver and associated RF front end to co-exist with the rest of the SoC while maintaining RF performance.

1-V Transceiver Exceeds Needs Of IEEE 802.15.6 Narrowband/BLE PHY

Fri, 26 Apr 2013 15:15:00 +0000

Fabricated in 0.13-micron CMOS and measuring just 5.9 square mm, this transceiver satisfies the IEEE 802.15.6 narrowband PHY standard as well as Bluetooth Low Energy to serve WBAN applications.

REVEALED: Source Of Low-Frequency 1/f Noise

Fri, 12 Apr 2013 12:57:00 +0000

A large number of applications require acceptably low levels of 1/f noise, as it contributes to the phase noise of communication systems and limits sensor sensitivity and selectivity.

Cross-Spectral Phase Noise Is Measured On Terahertz Source

Tue, 09 Apr 2013 13:15:00 +0000

With traditional phase-measurement systems generally unable to perform beyond 125 GHz and spectrally pure sources increasing in frequency, the race is on to conquer phase-noise testing of terahertz sources.
