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 ...

A New Planar Antenna Element For Ka-Band Applications

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...

The Wireless Synchronization Problem

Rachid Guerraoui, Seth Gilbert

In this paper, we study the wireless synchronization prob- lem which requires devices activated at different times on a congested single-hop radio network to synchronize their round numbering. We assume a collection of n synchronous devices with access to ...

A very wideband antenna with dynamically-controllable band rejection

Julien Perruisseau-Carrier

A very wideband slot antenna with reconfigurable stopband is presented. The reconfiguration is achieved by modifying the effective length of an embedded stopbandresonator by means of three pairs of PIN diodes. Four different operative states—three of them ...

Centre frequency and bandwidth tunable bandpass filter based on RF MEMS (10-14 GHz)

Mihai Adrian Ionescu, Catherine Dehollain, Montserrat Fernandez-Bolanos Badia, Suat Ayoz

This paper presents a novel tunable bandpass filter design with independent control of both the centre frequency and the bandwidth by means of analogue-series and digital-shunt MEMS capacitors. The filter is designed for operation in X and Ku bands with 4 ...

Stochastic simulation experiment to assess radar rainfall retrieval uncertainties associated with attenuation and its correction

Alexis Berne

As rainfall constitutes the main source of water for the terrestrial hydrological processes, accurate and reliable measurement and prediction of its spatial and temporal distribution over a wide range of scales is an important goal for hydrology. We invest ...

High Data Rate RFID Tag/Reader Architecture Using Wireless Voltage Regulation

Catherine Dehollain, Michel Declercq, Nicolas Pillin

This paper discusses a novel tag/reader system, based on the passive, far-field RFID principle, with megabits per second read capability at operating ranges of several centimeters. The system operates in the ISM band at 2.45 GHz. A maximum data rate of 4 M ...

A dynamic supply CMOS RF power amplifier for 2.4GHz and 5.2GHz frequency bands

Maher Kayal, Cédric Meinen

An implementation of a dynamic supply RF power amplifier (PA) in 0.11 mu m CMOS technology occupying a total area of 1.35mm(2) is presented. Two-tone measurement results at 2.4 and 5.2GHz show that the system can deliver over 16dBm linear output power with ...
