Phased-Array Antennas for Advanced Extremely High Frequency Satellite Communications
Abstract
Major Goals: 1. Development of RF SOI CMOS dual-polarization microwave monolithic integrated circuit (MMIC)phased array beamformers in separate transmit and receive chips. 2. Research and development of high-power (24 dBm Psat and 22 dBm OP1dB) stacked-FET PAs operating with high peak and average efficiency and 10,000 hour reliability. 3. Demonstration of assembled PAB steering for SATCOM array factor masks through agile digitally-programmed (6-bit) phase shifting and amplitude tapering through digitally-programmed (6-bit) gain control. 4. Preliminary design and layout of a custom US Army SOTM 8-element (4-channel dual pol.) phased-array transmitter array RFIC on a 45-nm SOI CMOS Trusted Foundry. The transmitter array will be designed for a per element peak output power of 24 dBm. 5. Preliminary design and layout of a custom US Army SOTM 8-element receiver array for operation at 20 GHz based on a 45-nm SOI CMOS Trusted Foundry supplier. The receiver array will operate with a 3 dB noise figure and offer a coherent IIP3 of -20 dBm. 6. Built-in self-test (BIST) for array calibration of phase and amplitude states over the beam steering space will be supported for die screening and in-situ calibration of process, voltage and temperature variations and stored in SRAM-based look-up tables (LUT) on-chip. The logic and calibration process will be demonstrated in phase I and synthesized following approval of the preliminary design. Digital predistortion can also be incorporated through LUT and will be investigated for integration in future phases. 7. PCB prototype for K/Ka-band PAB for proof-of-concept with antenna elements and up-conversion/down conversion using commercial off-the-shelf (COTS) direct conversion modulators and demodulators and COTS I/QADCs will be developed. Electromagnetic performance for an individual antenna element, the antenna array, and transition to the packaged IC will be modeled.
