11% efficiency 100GHz InP-based heterostructure barrier varactor quintupler
Research output: Contribution to journal › Article
A record conversion efficiency of 11.4% at 100 GHz using a heretostructure barrier varactor (HBV) quintuplet is demonstrated. The quintupler is based on a microstrip circuit mounted in a full-height crossed-Nvaveguide block. The nonlinear element consists of a planar HBV diode fabricated in InGaAs/InAlAs/AlAs epitaxial layers on an InP substrate.
