Filed:

Jan 20, 2005

Appl. No.:

10/543343

Inventors:

Frank D. Stroili - Hollis NH, US
James M. Huggett - Brookline NH, US

Assignee:

BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH

International Classification:

G01S 7/42

US Classification:

700 90, 342 13, 342155

Abstract:

What is provided is a receiver-on-a-chip comprising a monolithic integrated circuit that reduces the receiver to a cigarette-pack-sized assembly mountable directly at an antenna element, with a much-increased operational bandwidth and instantaneous bandwidth, increased dynamic range and with a two-order-of-magnitude decrease in size and weight. Moreover, because of the elimination of all of the I/O drivers and attendant circuitry, power consumption is reduced by two-thirds, whereas the mean time before failure is increased to 10,000 hours due to the robustness of the monolithic integrated circuit and use of fiber optics.

Abstract:

A radar warning receiver is implemented in low cost integrated circuit form utilizing only one analog component, namely a limiting amplifier. By taking the output of the limiting amplifier and utilizing monobit sampling of the output it has been found that one can provide an integrated circuit single chip radar warning receiver using delay correlation to extract frequency, amplitude and modulation type from signals at or below the noise level.

Appl. No.:

10/845941

Inventors:

James Huggett - Brookline NH, US

International Classification:

G01R013/02

US Classification:

702067000

Abstract:

The present invention relates to a device and method that digitally replicates the analog processing that is normally associated with an instantaneous frequency measurement device. Specifically, the present relates to a digital frequency measurement device comprising: a filter, where the filter receives an input RF signal and transmits an output signal centered around a desired frequency; a limiting amplifier downstream of the filter, where the amplifier receives and amplifies the output signal; a deserializer downstream of the amplifier that continuously samples the output signal from the limiting amplifier; and a digital frequency measurement processor (DFM), where the DFM receives data at a rate of 1/16 of the deserializer sample rate. The DFM transforms the data into multiples stages that are combined in order to produce an estimate of the input signal, where the DFM is implemented through a digital processing device.

Inventors:

- Nashua NH, US
James M. HUGGETT - Brookline NH, US

International Classification:

H01P 1/203

Abstract:

LTCC coupled stripline resonator filters for use as bandpass filters are implemented with combline topology or with interdigital topology. The filter bandwidths range from about 0.3 GHz to about 4.5 GHz, or higher, depending of the manufacturing limitations with frequency operation of about 0.1 GHz to about 100 GHz. The filters have a plurality of through plated vias extending through the filters and connecting the top and bottom ground layers to form electric walls thereby reducing the coupling between the adjacent resonators.
