Power-Combined Sources and Compact Economical Source in the mm-Wave Frequency Range (200–300 GHz)

In this work a set of two sources based on Schottky barrier diodes covering the frequency ranges of 200-235 GHz and 230-265 GHz with more than 23 dBm and 22 dBm output power levels, respectively, are presented. Following the already developed compact sources in the 200-300 GHz, the typical available output power of 16 dBm has been easily increased in more than 5dB by the combination of four tripler chips in one single module. Moreover, a compact commercial source in the frequency range of 270-297 GHz with nominal output power of 10 dBm is presented. The small deviation in measurement results from unit to unit, beside the low production costs, establishes this source as a reliable and reproducible product for high-volume-applications in this frequency range.
