Abstract:
JPL continues to develop robust planar, all solid-state sources to cover the 1414 to 1908 GHz band. These sources will be used as local oscillators to drive hot electron bolometer (HEB) heterodyne mixers on the Herschel Space Observatory to observe high-resolution spectra in the interstellar medium such as the N+ and C+ fine structure lines at 1461 and 1901 GHz, water lines at 1661, 1670, and 1717 GHz, and OH lines from 1834 to 1838 GHz. We report our current progress and present recent results. Results include a 175 K measurement of 88 µW at 1544 GHz and a room temperature measurement of 1 µW output power at 1810 GHz.
