A High Dynamic Range Tuner for Tactical Unmanned Air Vehicles (TUAV)

"Shared Spectrum Company and Synergy Microwave Company propose to design a low power, low cost tuner with very high dynamic range and low noise figure for small tactical UAV SIGINT applications. The focus of the project is the design of an innovative highintercept point mixer and a preamplifier with very low noise and high dynamic range. Both will cover the frequency range of HF to 40 GHz. The tuner will have a very high input third order intercept point and a low noise figure from HF to 6 GHz, that willprovide an 81 dB spurious free dynamic range (10 MHz bandwidth), which is at least 10 dB better than any receiver in the world covering this frequency range. By using a modular down converter, the tuner's range will be extended to 40 GHz, but with reducedperformance. The prime power requirements for a four-channel system will be approximately 60 W. Because the design will use high-volume design practices and highly integrated circuits, the tuner production cost will be low " $20 k). The mixer and amplifierdeveloped in this project will be widely applicable to commercial and military applications, such as cellular phone base stations, advanced multi-band transceivers, and the DoD's JTRS radio. During Phase I, extensive simulations using advanced non-linearsimulation tools will be used to verify the tuner performance and the initial design layouts will be made. Assisting in this program is Dr. UIrich Rohde, a world-renowned receiver desi
