Monolithic S-band Multichannel Transmit/Receive Module for Communication Phased Array Antennas

ABSTRACT: Phase II tasks will produce a full-duplex, multi-channel, S-band transmit-receive (T/R) module for integration into large communication phased array antennas. An RF section featuring advanced, two-chip Monolithic Microwave Integrated Circuit (MMIC) technology will replace the large number of discrete radio frequency (RF) components in existing systems. An embedded command microcontroller will provide internal protection and built-in test capability as well as serial-to-parallel command conversion. Design of the module will include interconnection and distribution circuits as well as the mechanical and thermal configurations. The anticipated advantages of this approach are size, weight, and cost reductions and maximized manufacturability, reproducibility, flexibility, and ease of replacement. In Phase I, the MMICs were designed to predict performance capability and circuit integration. The module capability will be demonstrated and evaluated in Phase II with prototype fabrication, assembly, and testing. BENEFIT: Auriga"s low-cost, full-duplex T/R module at S-band will drive down size and cost for large phased-array systems. The module will be well-suited for quick adaptation to many systems in the L- to X-band range, requiring multiple concurrent communication links capable of transmitting and receiving multiple beams simultaneously.
