Accordingly, NASA and ESA have developed a wide range of spectroscopic sounding instruments to investigate our solar system. Current LO chains for spectroscopic receivers are implemented with discrete III-V devices and heavy waveguide assemblies. For instance, the 600GHz NASA PISSARRO spectrometer for Europa begins with a 33GHz PLL, tripled to 100GHz,
