W-band Receive Phased Array for SATCOM Uplinks

Description:

TECHNOLOGY AREA(S): Sensors 

OBJECTIVE: Develop innovative wafer-scale antenna and front-end components for a multi-element receive phased array for future W-band SATCOM uplinks. 

DESCRIPTION: Future military SATCOM concepts include V-band (71-76 GHz) downlinks and W-band (81-86 GHz) uplinks to support next-generation high-data-rate communications systems. These systems will extend to new SATCOM frequency spectrums to address frequency crowding at lower frequencies. Additionally, currently demonstrated array front-end components at these frequencies have relatively low output power. Further, while single-point RF receivers with gimbaled antennas address a potential W-band receiver architecture, phased array architectures are also viable for these satellite communications concepts. This Phase I SBIR focuses on defining advanced architecture and performance goals for a communications W-band receive phased array, designing wafer-scale antenna and front-end components, and defining a proof-of-concept multi-element demonstration vehicle. At a minimum, the array components/functions should include multi-beam, multi-channel receiver. Due to high atmospheric propagation at these frequencies, ultra-low noise amplifier and low power consumption technology and should be considered. Further, ± 9 degree scanning angles and 0.1 degree 3-dB-beamwidths should be included in the phased array architecture definition. Operating environment goals include a temperature range of -40 degrees to +85 degrees Celsius. The selected solid-state technologies should also support reliable space operation and operation in radiation environments. Radiation hardening goals include greater than 1 Mrad total dose radiation tolerance. 

PHASE I: Definition of the W-band phased array receiver architecture and performance goals, definition of a multi-element demonstration vehicle, and the design of required antenna and front-end components. 

PHASE II: Development and demonstration of the wafer-scale antenna and front-end components, as well as the multi-element W-band receive phased array designed in Phase I. 

PHASE III: Links technologies under this effort will further benefit applications in nearby frequency bands. Military: Military millimeter-wave phased array applications include W-band satellite communications uplink electronics for future high-data-rate communications systems. Commercial: Commercial W-band phased array applications potentially include commercial satellite communications services and 5G backhaul communication .
