US Patent:

39381501, Feb 10, 1976

Filed:

Jun 25, 1974

Appl. No.:

5/482974

Inventors:

Chester C. Phillips - Rockville MD
William H. Zinger - Columbia MD
Robert F. Platte - Laurel MD
Melrose M. Jesurun - Silver Spring MD
Dennis H. Matthias - Columbia MD

Assignee:

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

International Classification:

G01S 740

US Classification:

343 177

Abstract:

A test set for an amplifier or other electronic device in which a waveform enerator furnishes a modulated RF signal to the item under test. Sensors extract samples of the RF signal at the item's input and output. A detector-mixer network compares and processes the input and output sample signals and produces signals at its output which are indicative of the phase distortion and amplitude distortion introduced by the item. The phase and amplitude distortion signals are sampled and held for each modulating signal pulse and are then processed to compile statistical data regarding the item's performance.

Assignee:

The Johns Hopkins University - Balimore MD

International Classification:

G06F 1560
H01P 316

US Classification:

364488

Abstract:

A computer aided design (CAD) method for designing circular overmoded waveguide systems having optimal operating characteristics. The CAD method receives selected input waveguide operational, material and structural parameters and computes the resulting waveguide operational characteristics, including power losses for a given waveguide system configuration, including both straight and bent sections. Optimal designs for lined dielectric and sheathed-helix types of circular waveguide and waveguide bends have resulted for both S- and X-band operation.
