Abstract
In this work, we present a fully integrated D-band
×12 SiGe-based frequency multiplier chain. It comprises two
frequency doubling and one frequency tripling stage. Each stage
uses an architecture that ensures high harmonic rejection at its
output and, thus, ultimately, at D-band frequencies. The focus
of this work is on describing the generation and propagation
of harmonic components in the multiplier chain. Measurements
show a maximum output power of 3.5 dBm and a 3-dB bandwidth
of 37.5 GHz cov
