Novel 1/f Noise Mitigation for THz Direct-Detection Receivers

A new noise-reduction technique for direct-detection receivers reduced 1/f ("flicker" or "pink") noise by 19 dB at 670 GHz. ...and can be applied to any direct-detection receiver in the terahertz frequency range. Researchers at NASA's Jet Propulsion Laboratory, Grumman Aerospace Systems, and Colorado State University developed technique to allow lower-power direct detection (rather than a higher-power-consumption heterodyne receiver) for NASA's Tropospheric Water Vapor and Cloud Ice (TWICE) small satellite instrument.

Cadence AWR Design Environment V15 Update

A V15 Update to the Cadence® AWR Design Environment® is now available. Containing more than 50 enhancements, the release offers greater design automation and customization for III-V, multi-technology modules, and RF PCB design/manufacturing flows, rapid analysis/verification of large circuit/EM designs, and design wizards.

Miniature Telemetry Tracks Insect Pollinators

A new battery-less 5.8-GHz transmitter is compact and light enough to let tagged ~90 mg honeybees fly. A compact, drone-borne phased-array antenna receiver tracked honeybees and bumblebees in free roaming and within their nests using angle of arrival estimation, received signal strength indicators.

Bolometer Arrays: THz Video Without Scanning

Current THz security video cameras use hundreds of detectors and optomechanical scanning to cover an adequate field of view. A new design uses a "fully-staring" 2D array of kinetic inductance bolometers with a single detector element responsible for each imaged pixel, increasing sensitivity. The test camera is designed to for a 2 m x 1 m field of view at 2.5 m at a near-video rate of 9 Hz.

Student Power Amplifier Competition Winners

Winners of MTT-S's 2020 High Efficiency Power Amplifier Student Design Competition (HEPA-SDC) were selected 16 Oct. after tests at Keysight's laboratory. The winners of Keysight's US$2,000 first-place prize were Haifeng Lyu and Yuchen Cao (University of Central Florida), advised by Kenle Chen. Second place went to William Sear, Devon Donahue, and Michelle Pirrone (University of Colorado, Boulder), advised by Taylor Barton.

Wolfspeed GaN Solutions Improving X-Band Systems SWaP-C

Wolfspeed has integrated decades of GaN on SiC design experience into our broad portfolio of HEMT devices and MMIC power amplifiers that support X-Band applications with smaller, lighter, more efficient and higher performing solutions.

Hollow-Core Antiresonant THz Fiber

A hollow-core antiresonant photonic crystal fiber (HC-ARPCF) was designed, simulated, and 3D printed from Zeonex. Experimental analysis via THz time-domain spectroscopy showed that the low-cost, easy-to-design-and-fabricate fibers can be used for sending low-loss THz signals over short distances for a variety of transmission and sensing applications.

Scalable Packaging for Integrated 73-GHz Tx/Rx IC

Intel engineers describe the multichip packaging of an E-band (71-76 GHz) mmWave phased-array transceiver with an integrated 4 x 4 antenna array. Each unit is populated with four identical 2.1 mm x 2.4 mm transceiver dies assembled on the bottom side of an 8.01 mm x 7.51 mm substrate--sized so that multiple units may be placed on a PCB to form a larger array while maintaining constant antenna pitch.

W-Band Rectenna Array for Wireless Power Transfer

A W-band rectenna unit incorporates a novel CMOS switching rectifier and a print tapered slot antenna to achieve the highest power conversion efficiency (PCE) among recently reported W-band technology systems. The high-reliability rectifier uses the body-diode effect (BDE) to improve PCE, and a high-gain antipodal linearly tapered slot antenna to improve the overall efficiency.
