D3.4: Report on fabricated MMICs and frontend performance

This deliverable summarizes the research on D-band fabricated RFICs and their measurement results used in ARIADNE, as an output in the second project phase of work in Task 3.2. Packaging of the radio frequency signal generation chain in combination with mandatory circuitry is also described in here, to finally build transmitter- and receiver-modules to be used for the planned project demonstrators of work package 5.

Deliverable 3.4 focuses on research activities regarding RFIC design, realization and performance measurements, which will cover all circuit design activities for the frontend modules. The project envisioned a multi-band radio that covers the major frequency sub-bands from 141 to 200 GHz (e.g. 141-148.5 GHz, 151.5-164 GHz, 167-174.8 GHz, 191.8-200 GHz).

The presented frontend RFICs were implemented in a high-speed 50 nm and 35 nm InGaAs HEMT technology on GaAs substrates fabricated in the IAF clean room facility. High-tech cost-efficient RF packaging is used to enclose the RFICs while maintaining their superior performance.

Coordinator of this deliverable is IAF. The technical quality is assured by the technical management UPRC Prof. Angeliki Alexiou and the WP / Task Leader IAF.
