International Classification:

G01R 2304

US Classification:

324 95

Abstract:

A radiation measurement means is shown which has the capability of detect radiation in both the millimeter wave, and the infrared, frequency regions. A basic self-oscillating Gunn diode is enclosed in a donut shaped silicon ring. The presence of infrared energy will create holes and electrons in the silicon material, altering its conductivity, and lower the power of oscillation. The realized drop in oscillating power identifies the infrared. Millimeter wave radiation is detected because an intermediate frequency is generated as the Gunn diode operates as a self-oscillating mixer of the new different frequency with its own oscillating frequency. Thus it is possible to detect signals from both ranges, in a single device.

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

H04B 126

US Classification:

455326

Abstract:

A triple Gunn diode self-oscillating mixer system is shown which can mix nals in the VHF range substantially without introducing any noise and with high input signal power handling capacity and with higher output mixed signal power than conventional, owing to boosted power from more than one microwave cavity. The device is comprised of three self-oscillating Gunn diode cavities connected by 180. degree. phase shift coax lines for injection locking. The device handles larger power levels without burnout as compared to conventional mixer devices such as Schottky barrier diodes having nearly 30 times less burnout capacity.

International Classification:

H01Q 326

US Classification:

343701

Abstract:

A millimeter wave line scanner is disclosed providing steered fan-shaped ms from opposite faces at substantially equal angles of a semiconductor waveguide, rectangular in cross section, and having a plurality of equally spaced metallic perturbations or strips disposed on one of the two radiating sides or faces. Different angles of scan are selectively obtained by means of at least one distributed longitudinal PIN diode formed on an adjoining side of the semiconductor waveguide having electrical circuit means coupled thereto for controlling the diode's conductivity which acts to change the guide wavelength and accordingly cause a variation in radiation angle of the two equal beams radiating in opposite directions and by means coupling energy of changing frequency to the semiconductor waveguide.
