Reconfigurable AESA Substrates
BV-RAF-4B16 enables next-generation fighter radar systems through reconfigurable T/R module substrates for multi-band operation, delivering enhanced performance across X, Ku, and Ka bands.
Active Electronically Scanned Array (AESA) radars demand substrates that can support rapid frequency reconfiguration while maintaining thermal stability across extreme operating conditions.
BV-RAF-4B16's adaptive geometry and dielectric tuning provide the foundation for multi-mode operation, enabling simultaneous air-to-air search, tracking, and electronic attack functions.
Application: Reconfigurable T/R Module Substrates
Key Requirements
- Multi-band operation: X, Ku, Ka band support
- Thermal management: -40°C to +125°C operation
- Rapid reconfiguration: Sub-microsecond switching
- High power handling: 10W+ per T/R module
BV-RAF-4B16 Advantages
- Adaptive dielectric constant (2.1-4.5)
- Thermal expansion matched to GaN
- Low-loss tangent across operating bands
- Integrated thermal vias for heat dissipation
