Multi-Band/Beam Module

The goal of this SBIR topic is to develop a phased array antenna module for multi-band/beam, dual polarized receive array at 15 GHz RHCP (Right Hand Circularly Polarized) and 20 GHz LHCP (Left Hand Circularly Polarized) and RHCP (Right Hand Circularly Polarized) supporting three simultaneous beam formations. Each antenna element requires an RF electronics package with three receivers, two at 20 GHz and one at 15 GHz. Each receiver chain needs to provide enough gain to establish system noise figure and overcome combiner network losses along with a digitally controlled phase shifter for beam forming. The multi band element receiver RF electronics would be fabricated on a single MMIC chip and packaged along with a digital latch for phase shifter control in a surface mount chip scale package. The custom MMIC would include two multi-stage LNA amplifiers with gain >24 dB. The first LNA would be used for the 20 GHz LHCP signal and the other would be used to amplify the RHCP signal for both the 15 GHz and 20 GHz bands. Critical to this development is the integrated subarray architecture which allows for modularity in the passive and active subassemblies for lower cost and maintainability.
