Abstract:
A primary challenge in creating the next generation of submillimeter-wave receiver systems for space science is generating the required local oscillator power. Broad-band performance and power levels suitable for array receivers are required. Also, the sources must be suitable for use at remote installations. This means they should be compact, reliable, electronically tunable and maintenance free. This talk will focus on our continuing development of terahertz sources with emphasis of "turn-key" operation, enhanced tuning bandwidth and output frequency to 1.9 THz. Virginia Diodes has developed a series of broadband frequency multipliers based on integrated diode circuits. A tripler to the WR0.5 waveguide band has recently been demonstrated. An amplifier/multiplier chain with this component, shown in Fig. 1, generates 1 - 3 uW of power at room temperature within the 1.8 - 1.9 THz band. Most importantly, it is extremely easy to use and requires no mechanical tuning or user controlled bias adjustments.
