This contribution presents a full chip set dedicated to high data rate indoor wireless communication at a carrier frequency of 300 GHz. The analog frontend consists of a three-chip solution, namely a transmitter, receiver and local oscillator frequency multiplier. The active millimeter-wave monolithic integrated circuits are realized in a GaAs-based metamorphic high electron mobility transistor technology...
This paper presents the design and measured performance of an H-Band (220–325 GHz) submilimeter-wave monolithic integrated circuit (S-MMIC) implementing a balanced variable-gain low-noise amplifier (VGA) based on Tandem-X couplers for use in next generation communication systems. This amplifier will be used as first stage in an integrated wideband receiver for 300 GHz wireless communication for indoor...
An innovative wireless authentication platform for healthcare applications is designed, implemented and tested. It acts as a Common Recognition and Identification Platform (CRIP) operating with write/read function via either NFC or biometric modules for the users' authentication. The CRIP base station architecture consists of 13.56MHz NFC/RFID and 2.4GHz IEEE standard 802.15.1 BLE modules. The Bluetooth...
A combined frequency divider and phase detector MMIC has been successfully realized in an GaAs mHEMT process with 100nm gate length, forming the base of a PLL carrier recovery for an E-band communication system. The frequency-divider-by-8 provides a sensitivity down to −54dBm - to the author's knowledge the highest sensitivity published in the E-band - and a bandwidth of 4.2GHz at a reference input...
Based on active millimeter-wave monolithic integrated circuits (MMICs), a pair of receiver and transmitter modules have been developed and used for wireless data transmission experiments at 240 GHz with data rates of up to 40 Gbit/s. Both modules are driven with a subharmonic local oscillator, located at 120 GHz and feature broadband quadrature I/Q IF terminals. The receiver module has a maximum conversion...

In this paper, we present monolithic integrated I-Q receive and transmit MMICs for wireless data transmission in the frequency range around 240 GHz. The chipset features an RF bandwidth of more than 80 GHz which corresponds to an IF bandwidth of more than 40 GHz. This enables the direct up and down-conversion of broadband IF signals like on-off keyed modulations. The receiver, as well as the transmitter,...
Wireless sensor networks (WSNs) have the capacity to revolutionize data gathering in both spaceflight and terrestrial applications. WSNs provide a huge advantage over traditional, wired instrumentation since they do not require wiring trunks to connect sensors to a central hub. This allows for easy sensor installation in hard to reach locations, easy expansion of the number of sensors or sensing modalities,...
Pervasive healthcare systems are trying to address the expected demand for caretaking and out-of-hospital monitoring. These systems allow for automatic and distributed monitoring of patients, but many of them are time consuming with regards to installation and maintenance configuration of the sensor network and communication platform. To avoid burdening caretaking staff and relatives with installing...
