Submillimeter Wavelength Surface-Oriented Diode Mixers
Autor: P. E. Tannenwald, Carl O. Bozler, G.D. Alley, R.A. Murphy, B. J. Clifton, H.R. Fetterman
Publikováno v: MTT-S International Microwave Symposium Digest.
Schottky barrier diodes in which proton bombardment has been used to define small surface-oriented devices have been used as submillimeter wavelength mixers. High-order harmonic mixing and direct heterodyne mixing with lasers up to 761 GHz have been

High Sensitivity Submillimeter Heterodyne Receiver
Autor: H.R. Fetterman, C. D. Parker, W. D. Fitzgerald, P. E. Tannenwald, B. J. Clifton
Publikováno v: MTT-S International Microwave Symposium Digest.
Radiometric sensitivity measurements have been made on a quasi-optical receiver in the spectral range 170 mu m to 1 mm. Using GaAs Schottky mixer diodes in a corner reflector configuration, a total system noise temperature of 9,700 K (DSB) has been o

Far‐ir heterodyne radiometric measurements with quasioptical Schottky diode mixers
Autor: B. J. Clifton, N. R. Erickson, C. D. Parker, W. D. Fitzgerald, H. R. Fetterman, P. E. Tannenwald
Publikováno v: Applied Physics Letters. 33:151-154
We have made heterodyne radiometric measurements with GaAs Schottky diode mixers, mounted in a corner‐reflector configuration, over the spectral range 170 μm to 1 mm. At 400 μm, system noise temperatures of 9700 K DSB (NEP=1.4×10−19 W/Hz) and

PRINTED DIPOLE MILLIMETER WAVE ANTENNA FOR IMAGING ARRAY APPLICATIONS
Autor: P. E. Tannenwald, R. H. Mathews, T.C.L.G. Sollner, H. R. Fetterman, C. D. Parker, P. T. Parrish
Publikováno v: Electromagnetics. 3:209-215
Planar antenna arrays have been developed at 140 GHz using twin-dipole elements. The initial systems have been fabricated using a hybrid approach with beam lead Schottky GaAs diodes mounted on quartz substrates. Heterodyne measurements of subelement

Ferromagnetic Resonance in Manganese Ferrite Single Crystals
Autor: P. E. Tannenwald
Publikováno v: Physical Review. 100:1713-1719
The microwave properties of two types of manganese ferrite single crystals have been investigated by means of the ferromagnetic resonance phenomenon from 300\ifmmode^\circ\else\textdegree\fi{}K to 4.2\ifmmode^\circ\else\textdegree\fi{}K and at 24 000

Physics of quantum electronics
Autor: B. Lax, P. L. Kelley, P. E. Tannenwald
Publikováno v: Physics Today. 18:58-62
The intent: to hold a gathering of a small number of active scientists to discuss the physics of quantum electronics in a setting that would afford a maximum opportunity for close contact in a relaxed atmosphere with a minimum number of formally sche
