“…Multipliers using two whiskered diodes in parallel have been reported [20]. An integrated array of four GaAs planar varactors has been used for a highefficiency frequency doubler [21] for 50-200 mW input powers, efficiencies of 20-25 per cent have been attained at 174 GHz. This doubler has been investigated theoretically using finite-element analysis of the varactor and supplemented by analogue measurements [22].…”

The performance of Schottky barrier varactor multipliers is compared, with emphasis on generating power at frequencies above 1 THz. Measured efficiencies at 800 GHz are >3 per cent at and decrease to 0.9 per cent at 1 . 13 THz and 0.25 per cent at 1 .4 THz. The power available from the penultimate multiplier in a chain imposes a limit on the output from the last stage. Further work is also required to overcome losses in multiplier structures and to understand better velocity and voltage saturation effects in varactors.

“…With the advent of high-quality submillimeter-wave planar diode technology, however, multidiode circuit fabrication has become realizable. Balanced multipliers and mixers utilizing planar diodes have demonstrated better performance than similar whisker-contacted structures up to 200 GHz [2], [3]. In this letter, a new approach is introduced where a planar frequency doubler circuit with a fully open antenna architecture combines device and circuit symmetries to yield an extremely simple and compact design with inherent port-toport isolation.…”

A novel quasi-optical all-planar frequency doubler that could provide an alternative approach to conventional waveguide circuits for millimeter-and submillimeter-wave signal generation is presented. The multiplier uses a quad-bridge diode configuration for inherent isolation between the input and output signals. Two pairs of double-slot antennas with orthogonal polarizations directly couple input and output signals to the diodes, without the need for hybrid couplers required in typical balanced circuits. The integrated quad-bridge-diode/slot-antenna circuit is mounted on a dielectric-filled parabola for coupling to quasioptical propagation systems. Measurement results for an X to K-band doubler show frequency conversion loss of 6.8 dB at the output frequency of 20.3 GHz.Index Terms-Dielectric-filled parabola, diode frequency multiplier, slot antenna.

“…However, at millimeter-wavelength Schottky planar discrete diodes started to give better performance due to the use of multiple anodes in balanced configurations. Erickson's balanced doublers, proposed and demonstrated in [48][49][50], have become a standard topology for frequency multiplication due to their good performance. Gallium arsenide (GaAs)-based heterostructure barrier varactors (HBVs) were introduced by Kollberg and Rydberg at the University of Chalmers [51], Sweden, as alternate diodes, and this technology took a significant turn in the late 1990s when Lippens and Mélique at IEMN, France, introduced indium phosphide (InP)-based multiple barrier devices [52].…”

We provide an overview on terahertz (THz) frequency metrology, starting from the nowadays available continuous wave THz sources, discussing their main features such as tunability, spectral purity, and frequency referencing to the primary frequency standards. A comparison on the achieved results in high-precision molecular spectroscopy is given and discussed, and finally, a special emphasis poses on the future developments of this upcoming field.
