Teledyne Scientific & Imaging Announces 50GHz Track & Hold Amplifiers for Wideband Signal Acquisition and Processing

THOUSAND OAKS, Calif. – August 23, 2022 – Teledyne Scientific & Imaging, a Teledyne Technologies (NYSE: TDY) company, is expanding its high-speed mixed-signal integrated circuits (IC) product offering with the addition of two Track & Hold Amplifiers with an unprecedented 50 GHz input bandwidth (BW) designed for wideband signal acquisition and processing.

  • RTH110 – Track & Hold IC, 50 GHz Input BW, Clock Frequency from 100 MS/s to 1 GS/s
  • RTH130 – Track & Hold IC, 50 GHz Input BW, Clock Frequency from 800 MS/s to 14 GS/s

​RTH110 – A three-stage Track-and-Hold Amplifier (THA) with an input bandwidth from DC to 50 GHz and a sampling rate from 100 MS/s to 1 GS/s. Total harmonic distortion (THD) is better than -40 dB at 30 GHz and -35 dB at 50 GHz, output signal is 1Vpp differential, and power dissipation ≤1.9 Watts. The RTH110 is ideally suited for broadband test-and-measurement applications to capture waveforms with less than 10 ps rise times.

RTH130 – A two-stage THA with an input bandwidth from DC to 50 GHz and a sampling rate from 800 MS/s to 14 GS/s. THD is better than -35 dB at 50GHz, output signal is 1Vpp differential, and power dissipation ≤1.5 Watts. The RTH130 eliminates the need for local oscillators and mixers in wideband systems making for compact cost-effective RF-to-digital receivers.

Both the RTH110 and RTH130 are available in 4x4mm quad flat no-lead (QFN) package. Die option and evaluation boards also available.

Teledyne Completes Delivery of Flight Detectors to the Roman Space Telescope

​​THOUSAND OAKS, Calif. - December 8, 2021 - The Nancy Grace Roman Space Telescope is NASA's next flagship Astronomy and Astrophysics space observatory, following the Hubble and James Webb Space Telescopes (HST and JWST). Launch of Roman is planned for 2027. Whereas HST and JWST focus on small regions of the universe with narrow field of view instruments, the Roman Space Telescope has a wide field of view, 100 times the field of view of Hubble. Roman's wide field of view, combined with the light gathering power of a 2.4-​meter primary mirror, will settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics. Roman will survey billions of galaxies and study thousands of exoplanets.

Roman's wide field of view required a new generation of infrared detector developed by Teledyne Imaging Sensors in Camarillo, California. The infrared sensor chip assembly (SCA) developed for Roman is the H4RG-10, 4,096 by 4,096 pixels, each pixel is 10 by 10 microns in size. (A human hair is about 100 microns wide.) Eighteen (18) H4RG-10 SCAs are in the focal plane mosaic of Roman, totalling over 300 million pixels. This is by far the largest infrared focal plane ever made, for space or ground-based facilities.​

Teledyne was awarded a $23 million contract in 2018 to supply 24 flight quality SCAs; 18 for flight and 6 flight spares. Teledyne achieved a high level of contract execution:

  • 28 flight quality SCAs have been delivered (4 more than required).
  • All 28 SCAs exceed the specifications for quantum efficiency (ability to detect photons), low noise (dark current, readout noise), and very low image persistence (also known as image lag or memory effect).
  • The ability of Teledyne's infrared detectors to also detect visible wavelengths has enabled Roman's wide field of view instrument to increase the spectral bandwidth by 20%.
  • Teledyne continued working throughout the pandemic, ensuring the infrared detectors were delivered before the dates needed for the Wide Field Instrument.

In addition to the infrared arrays, Teledyne is producing the visible light detectors that will be used in the coronograph instrument of the Roman Space Telescope.

"Teledyne is proud to provide the high performance infrared detectors for the Roman Space Telescope," said Dr. John Auyeung, Teledyne's Director of Astronomy & Earth Observation and Program Manager for Roman SCA development and flight production. "I have been fortunate to serve as the program manager for the infrared arrays supplied to Hubble, JWST, and Roman. The partnership with Goddard Spaceflight Center has been the highlight of my career."

Enhance Memory and Skill Learning While Sleeping

Researchers at Teledyne Scientific & Imaging, LLC have developed a new approach that enhances memory and skill learning while people sleep. In experiments conducted on over 100 human subjects, they demonstrated an up to 25% improvement in memory compared to subjects that did not use the new device.

The approach leverages a phenomenon in the brain called memory replay which is thought to be involved in the transfer of information from short-term to long-term memory (a process termed consolidation) that takes place during sleep. The research focused on detecting biomarkers that indicated the brain was in the critical period of memory consolidation. Then,  by applying either a short sound or noninvasive electrical stimulation, they could trigger a boost in learning. The research suggests that this closed-loop approach, which tightly couples and prescribes interventions based on ongoing brain activity in real-time, significantly improves learning in real-world tasks in people.

The research was conducted as part of a large scale collaboration with researchers from RioGrande Neurosciences, the University of California at Riverside, and Intific Inc., and funded by the Defense Advanced Research Projects Agency's (DARPA) Restoring Active Memory (RAM) Replay program.

As part of their ongoing research, Teledyne has demonstrated that this approach improves learning across a number of domains. First, it improved learning to navigate a new 3D environment simulated in virtual reality. Here, participants who received the closed-loop intervention realized an almost 40% benefit in their navigation time compared to controls, indicating an increase in understanding and retention of the virtual city layout. Second, they have also demonstrated significant effects in boosting memory on more standard educational material. For example, they found that noninvasive electrical stimulation could improve an individual's test scores on lecture material by >10% (a full letter grade improvement) two days after the material was learned without any additional study of the material.  Finally, ongoing work is demonstrating an over 15% improvement on memory tests of facts.

 “Through this research we have gained great confidence that these approaches can make a difference in people's lives by enhancing learning on a number of different tasks.", says Dr. Stephen Simons who is the lead investigator for Teledyne's team on the project. “Furthermore, the noninvasive nature of these interventions and their application during sleep means that these benefits can be realized with minimal disruption to people's everyday routines."

Through part of the research, Teledyne has developed a prototype headband system that can easily and comfortably be worn while an individual sleeps. They are actively seeking partners to test and transition the technology to commercial applications.
