Ultra-Low Power Short-Range 60-GHz FMCW Radar Front-End

The millimeter wave (mmWave) frequency band is becoming very interesting over the past years because it provides the opportunity to operate using large bandwidths which are not available at lower frequencies. This enables new communication standards suppor ...

Comparison of L1 and L5 Bands GNSS Signals Acquisition

Cyril Botteron, Jérôme Leclère

Nowadays, civil Global Navigation Satellite System (GNSS) signals are available in both L1 and L5 bands. A receiver does not need to acquire independently the signals in both bands coming from a same satellite, since their carrier Doppler and code delay ar ...

Full C and L-Band Transmission at 20 Tbit/s Using Cavity-Soliton Kerr Frequency Combs

Tobias Kippenberg, Victor Brasch, Maxim Karpov, Arne Kordts, Mirjam Pfeiffer

Temporal soliton formation in a Kerr-nonlinear optical micro-resonator leads to a coherent frequency comb covering the C and L-band. We demonstrate WDM transmission with 94 comb lines and an aggregate data rate of 20 Tbit/s. ...

Lens-based Ka-band antenna system using planar feed

Juan Ramon Mosig, Marc Esquius Morote, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper presents a simple, low-cost and compact mobile ground terminal antenna for Ka-band satellite communications that operates in the downlink band (19.7-20.2 GHz). The antenna is composed of a shaped dielectric lens which tilts in front of a planar ...

Broadly tunable source around 2050 nm based on wideband parametric conversion and thulium–holmium amplification cascade

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette

We report the design of a short-wave infrared continuous-wave light source featuring a 20 mW average output power, and with a wavelength that can be freely selected in the 2000-2100 nm range amid a low power ripple. The operating principle relies on the si ...

High-Q Adaptive Matching Network for Remote Powering of UHF RFIDs and Wireless Sensor Systems

Catherine Dehollain, Onur Kazanç, Franco Maloberti

Process and temperature independent RF front-end design is important for remotely powered RFID tags and wireless sensor systems. Run-to-run process variations can impact the remote powering performance and therefore read range of aforementioned systems. We ...

Contribution to modeling multipactor and corona discharges in high power electromagnetic fields

Francisco Edén Sorolla Rosario

Multipactor and microwave corona breakdown are two high frequency discharges occurring within microwave components for space applications as well as within particle accelerators. The appearance of these phenomena results in the exponential growth of the el ...

Power Sub-Miniature (PSM) Connectors for Space Applications

Michael Mattes, Francisco Edén Sorolla Rosario

This paper presents a newly developed SMA-like connector for High Power Space applications that can withstand more than 1500 Watts in the P- and L-Band for a pulsed signal of 2% duty-cycle. This implies an improvement of 50 per cent compared to other power ...

Frequency- and Time-Domain Measurement of Bare Soils and Wheat Canopy Using Monostatic Horn Antenna GPR - Implications and Applications for Radar Remote Sensing

Dani Or

GPR with a suspended 1 GHz horn antenna was deployed in the greenhouse and field for measurement of near-surface hydrologic parameters over bare and wheat canopy covered soils. Analyses of time-domain (TD) surface reflections (SR) and signal propagation ti ...
