Frequency multipliers up to 500GHz
Under development, not publish yet
15VAxx diode structure is developed for frequency multipliers up to 500GHz. This represents a so-called “T-structure” with two in series-connected varactor anodes per each arm and three contact pads. This approach reduces mounting complexity and improves reproducibility of balanced multipliers.
15VAxx diodes are fabricated by traditional planar technology and implemented on thinned down to 20µm s.i. GaAs substrate. Air-bridge interconnected mesas provide for a low parasitic capacitance and are fully passivated against harsh environment. Contact pads are gold finished.
15VAxx diodes can be mounted onto submount substrate by flip-chip soldering or gluing using conductive epoxies.
