Biasable Subharmonic Membrane Mixer for 520 to 600 GHz

advertisement:

This is a prototype of mixers for future submillimeter-wavelength spectrometers.

The figure shows a biasable subharmonic mixer designed to operate in the frequency range from 520 to 600 GHz. This mixer is a prototype of low-power mixers needed for development of wide-band, high-resolution spectrometers for measuring spectra of molecules in the atmospheres of Earth, other planets, and comets in the frequency range of 400 to 700 GHz.
