Miniaturized Multi-channel Tuners/Receivers for Tactical Unmanned Aerial Vehicle (TUAV) Applications

"Proposed here is a synthesizer for a wide bandwidth 0.02 to 40 GHz Receiver capable of converting the 40 GHz spectrum to baseband in one GHz increments. This novel architecture requires a minimum number of synthesized frequencies to accomplish theconversion. The architecture also minimizes internally generated spurious and spurious resulting from image band interfering signals. Two alternate synthesizer architectures will be evaluated as part of this phase one contract, direct and indirect. Aselection will be made based on relative performance compared with requirements. The direct synthesizer approach offers the ultimate in speed and phase noise performance but comes at the expense of power consumption and size. The indirect approachcompromises speed and noise performance for much smaller size and power consumption. Another factor, which will be investigated, is the best choice for the Master Oscillator. This is another area where power consumption, size and complexity can be tradedfor performance. Components developed on a Phase II follow on program would be various components for commercial and military synthesizer applications such as: Low Noise MMIC VCOs, Phase-Frequency Detectors, Phase Locked Loop ICs, Low noise Prescalers,Phase Locked Oscillators"
