Filed:

Jun 11, 1996

Appl. No.:

8/660972

Inventors:

Rodney K. Bonebright - Milton WA
Rodney A. Hughes - Tacoma WA
Jay W. Clement - Kent WA
John H. Nitardy - Seattle WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

H04B 1000

US Classification:

359152

Abstract:

A transceiver (14) for recovering two different types of manchester coded, optical data signals from a photodiode is disclosed. The transceiver (14) includes a preamplifier (28) that receives and differentially amplifies the optical signal to reject power supply noise. The output of the preamplifier (28) is applied to an AC coupler (30) that extracts DC signal components using a switching circuit to produce a purely differential signal. A post amplifier/quantizer (34) receives the purely differential signal from the AC coupler (30) and generates a quantized signal therefrom. The quantized signal is applied to a data filter, clock recovery and control logic system 36 (36) that recovers a clock signal from the data signal that is synchronized by every data edge of the quantized signal.

International Classification:

H01Q 21/00
H04B 7/06
H01Q 3/36

Abstract:

A phased array antenna system includes a plurality of radio frequency (RF) tile sub-arrays. Each RF tile sub-array includes a multiplicity of RF elements, a tile control integrated circuit, a multiplicity of RF integrated circuits and a configuration storage device. The configuration storage device stores data including calibration and configuration information that is unique to the RF tile sub-array and the tile control integrated circuit. The multiplicity of RF integrated circuits, the multiplicity of RF elements, and the configuration storage device are disposed on a single associated RF tile sub-array. The system also includes an antenna controller configured to process data for steering or tracking one or more RF beams by the multiplicity of RF elements. The calibration and configuration information that is unique to the RF tile sub-array is downloaded from the configuration storage device through the tile control integrated circuit to an RF element compensation table.

International Classification:

H01Q 3/34

Abstract:

A phased array antenna system may include a plurality of radio frequency (RF) tile sub-arrays arranged in a certain pattern to define an RF aperture. Each RF tile sub-array may include a multiplicity of RF elements and each RF element may be separately controlled for steering or tracking an RF beam generated or received by the RF element. The phased array antenna system may also include an antenna controller configured to process data for steering or tracking one or more RF beams by the multiplicity of RF elements. The antenna controller may additionally include a plurality of aperture state machines. An aperture state machine may be associated with each RF tile sub-array for controlling operation of the associated RF tile sub-array. The phased array antenna system may further include a plurality of RF tile buses. One RF tile bus operatively couples each aperture state machine to the RF tile sub-array.
