Abstract:
Heterodyne receivers operating at THz frequencies can detect rotation spectra of several spurious gases. These receivers typically use sub harmonic Schottky diode mixers, which need a low phase noise local oscillator (LO) input generated by frequency multiplication and amplification. THz radiometry requires broadband receivers with low noise temperatures which are necessary for high temperature resolutions. All these systems benefit from low-noise transistors working at millimeter-wave (MMW) frequencies.
