Active Electronically Scanned Arrays (AESAs)
CAES AESAs enable tremendous operational flexibility at an unprecedented performance-to-price ratio.
- Unique, wideband AESA technology, ideally suited for electronic warfare applications
- Blended technology approach to RF construction with extensive utilization of COTS SMT devices
- All GaN RF PowerStage, using either COTS or custom GaN devices as needed to address customer specific SWaP requirements
- Highly-integrated, multicore ICs provide high-speed, high-resolution, beam steering
- Integrated gigabit Ethernet interface for command and control
- MOSA compatible, enabling future system upgrades and technology insertion
- Liquid and air cooling options available to suit specific applications
- High mean time between failures (MTBF) with graceful degradation
Our AESAs are based on our field-proven monolithic microwave integrated circuits (MMICs) which enable unprecedented integration of aperture-to-data signal chains, including Ka- and W-Bands. Offered as both complete solutions as well as custom MMICs for AESA design, they feature:
- Modular, scalable, system-on-chip (SOC) solution
- SoC technology includes flip-chip and bumped die configurations
- Multichannel GaN-based transmit/receive MMIC technology
- Multiple Input, Multiple Output (MIMO) technology offers extended virtual receive channels
- High speed beam steering and control with a single steering vector for the entire array
