Investigation of mm-wave RTD based amplifiers

This work explores the applicability of Resonant Tunnelling Diodes as active elements in two different amplifier configurations in the range 25 GHz-35 GHz, with a view of implementing scaled versions at W-band and beyond, as frontend narrow-band low-noise amplifiers. On-wafer S-parameter measurements are used to represent devices in simulation software for increased fidelity. Initial results are promising, showing close to 10 dB gain at 30 GHz.
