摘要： Low cost millimeter wave imagers using two-dimensional focal plane arrays based on backward tunneling diode (BTD) detectors. Two-dimensional focal arrays of BTD detectors are used as focal plane arrays in imagers. High responsivity of BTD detectors near zero bias results in low noise detectors that alleviate the need for expensive and heat generating low noise amplifiers or Dicke switches in the imager. BTD detectors are installed on a printed circuit board using flip chip packaging technology and horn antennas direct the waves toward the flip chip including the BTD detectors. The assembly of the horn antennas, flip chips, printed circuit board substrate, and interconnects together work as an imaging sensor. Corrugated surfaces of the components prevent re-radiation of the incident waves.

摘要： An apparatus comprises a structure, an array of oscillator units, a plurality of waveguides in the structure, and a synchronizing cavity located within the structure. The array of oscillator units has a plurality of rows and a plurality of columns associated with the structure. Oscillator units in a row within the array of oscillator units are directly coupled to each other. The plurality of waveguides is configured to couple the array of oscillator units to the synchronizing cavity. The synchronizing cavity is configured to cause the array of oscillator units to operate at substantially a common frequency.
