“…The Schottky diode frequency doublers at 180 and 360 GHz were fabricated on gallium arsenide (GaAs) substrates, each with four-anodes in typical anti-series configuration commonly used in frequency doublers [3]. The GaAs circuits were suspended in the metal block via beam-leads that extended from the semiconductor circuit providing mechanical support and RF grounds.…”

“…The substrate is mounted on the lower block with silver epoxy. The substrate is doublesided suspended stripline with the same circuits printed on both sides, including the input E-probe, the input LPF (LPF1) for suppressing the third harmonic and impedance matching, the Schottky diodes, the output E-probe and the hammer-head LPF (LPF2) for bias line to prevent the input signal from leaking to the bias terminal [25].…”

Abstract-We propose a balanced frequency tripler scheme for millimeter-wave and submillimeter-wave application, in which doublesided suspended stripline is adopted. Two arms of Schottky diodes are mounted on the upper side of the substrate, and the other two arms of diodes are mounted on the lower side. The diodes are DC biased without bypass chip capacitor, which is essential in the common used balanced tripler scheme. Furthermore, the numbers of the diodes are doubled as there are only two arms of diodes in the common balanced tripler scheme, and this will double the power handling capability of the tripler. A W-band frequency tripler is designed according to the proposed scheme with commercial Schottky Varistors. The output power is from 2.9 to 5.7 dBm at the frequencies from 89.7 to 94.8 GHz, with the conversion efficiency from 1.95% ∼ 3.7%.

“…More remarkably it is now possible to design and build very high power multipliers in the 150-320 GHz range that can be used to drive next stage multipliers. 80 mW at 140 GHz, 76 mW at 1 80, and 15 mW at 270 have already been demonstrated and a number of slightly different approaches based on the balanced doubler concept have been demonstrated with very impressive results [7,8,9].…”

“…The doubler block designed for the 92-106 GHz bandwidth (this corresponds to the first stage multiplier for Band 5 in Table 1) is based on the design discussed in some detail for a lower frequency band [21]. The design and measured performance of this particular multiplier circuit will be discussed briefly.…”

“…Ports were attached to probes on each anode so that the individual embedding impedances for each varactor could be monitored directly. More detailed embedding impedances simulations for this block have been presented in Reference [8]. The diodes were then embedded into the resulting cascaded S-parameter matrix blocks to determine the total efficiency and power performance of the multiplier.…”

Development of millimeter- and submillimeter-wave local oscillator circuits for a space telescope

et al. 1999

FIRST (Far InfraRed and Submillimetre Telescope) is a European science mission that will perform photometry and spectroscopy in the 80-670 tm range. The proposed heterodyne instrument for FIRST is a seven-channel receiver, which combines the high spectral resolving capability (O.3-300km/s) of the radio heterodyne technique with the low noise detection offered by Superconductor-Insulator-Superconductor (515) and Hot Electron Bolometer (HEB) mixers. It is designed to provide almost continuous frequency coverage from 480-2700 GHz. The Jet Propulsion Laboratory is responsible for developing and implementing the local oscillator sources for the 1200-2700 GHz mixers. The present state-of-the-art approach for millimeter-wave multipliers, based on waveguide blocks and discretely mounted devices, becomes harder and harder to implement as the frequency range is extended beyond 300 GHz. This talk will focus on the technology that is being developed to enhance and extend planar integrated Schottky devices and circuits to meet mission local oscillator requirements. The baseline approach is to use GaAs power amplifiers from 7 1 to 1 15 GHz followed by a series of planar Schottky diode varactor multiplier stages to generate the required LO signal. The circuits have to be robust, relatively easy to assemble, and must provide broad fix-tuned bandwidth. A number of new technology initiatives being implemented to achieve these goals will be discussed. Approaches include quartz-based and substrate-less diode circuitry and integrated GaAs membrane technology. Recent results and progress-to-date will be presented.
