High Performance Heterostructure Barrier Varactors

Didier Lippens, Xavier Mélique, S. Arscott, Thibaut David, V. Duez, Jorge Carbonell, Patrick Mounaix, Olivier Vanbésien, Francis Mollot

We report on the physics, fabrication technology and characterisation of high performance Heterostructure Barrier Varactors diodes. State-of-the art results in terms of capacitance ratios of up to 10:1 and voltage handling have recently been published for InP-and GaAs-based devices with a typical…

A 5 mW-290 GHz heterostructure barrier tripler in a waveguide configuration

T. David, M. Guillon, S. Arscott, Alain Maestrini, Tahsin Akalin, Benoît Lecomte, Jorge Carbonell, Michel Chaubet, Patrick Mounaix, Gérard Beaudin, Didier Lippens

An output power of 5 mW has been demonstrated at 290 GHz by tripling a primary signal in the W band. The nonlinear devices are high performance InP-based heterostructure barrier varactors mounted in mechanically tuned waveguide harmonic multiplier. The flange-to-flange maximum efficiency was 5%…
