Patent ID: 7023374

Claim:
Apparatus for multi-band, multi-frequency signal detection and transmission, comprising: a multi-band wideband antenna for receiving said signals; a receiver, connected with said antenna, said receiver comprising: a plurality of low-noise amplifiers (LNAs); a DDS driven by a reference source; a plurality of synthesized down-converters, each of said plurality of down-converters connected with a respective one of said LNAs; a plurality of synthesized programmable multi-channel phase-locked LOs based on said DDS, wherein each of said plurality of down-converters is connected with a respective one of said synthesized progran-iniable multi-channel LOs and wherein each of said LOs is synchronized with said DDS; and a synthesized complex I/Q phase-detector comprising an LO, said phase-detector synthesized LO based on said DDS, said phase-detector connected with said down-converters; a control center comprising: a powerful DSP; a memory unit connected with said DSP; analog-to-digital converter (ADC) connected with said I/Q phase detector and with said DSP; a plurality of digital-to-analog converters (DACs) connected with said DSP; and FPGA connected with said DSP and with said plurality of programmable synthesized receiver LOs, said FPGA additionally connected with said DDS for programming controls; and a multi-band transmitter comprising: a plurality of synthesized programmable multi-channel transmitters based on said DDS, each of said transmitters synchronized with said DDS and each of said transmitters connected with said FPGA for receiving programming controls; and a plurality of multi-band wide-band antennae for transmitting.
