Technical Description
Core Processing Architecture
The system utilizes Xilinx Zynq UltraScale+ MPSoC devices, combining dual Cortex-A72 application processors with a configurable logic block to deliver hard real-time processing capability. Paired with Infineon IMZA120R007M1H SiC power modules, it achieves 100kHz-class switching frequency and <0.8mJ/pulse energy loss, meeting the pulse modulation demands of active electronically scanned array (AESA) radar TR modules.
Signal Integrity Optimization
A 12-layer high-density interconnect (HDI) board employs Rogers RO4350B™ high-frequency substrate (relative dielectric constant ε=3.48±0.05), ensuring <0.1dB/cm insertion loss at 10GHz. Laser direct imaging (LDI) technology achieves ±5μm trace width accuracy, while FR4-TG180 and PTFE hybrid lamination technology controls Z-axis coefficient of thermal expansion (CTE) to <35ppm/°C. The power distribution network (PDN) impedance is designed ≤1mΩ, supplemented by 60dB magnetic shielding to suppress electromagnetic interference (EMI) below 18GHz.
Environmental Robustness
Compliant with MIL-STD-810H military standards, the design withstands 500 cycles of -65°C↔+150°C thermal shock and 2000-hour 85%RH/85°C humidity aging. It achieves IP67 protection rating (1m water immersion/30min) and 40G half-sine wave mechanical shock resistance (11ms pulse width). Electrical safety includes 6kV surge protection and 2500VAC isolation barrier.
Manufacturing & Certification
Fabricated to Class 3 military PCB standards (MIL-PRF-31032), the process incorporates 3D X-ray inspection (solder joint void rate ≤2% per IPC-7095 Class 3) and automated optical inspection (AOI false call rate <0.1%). Certifications cover NATO STANAG 4290, ETSI EN 303 363, and FCC Part 87 regulations, with full compliance to RoHS III and REACH SVHC. The service portfolio includes 24-hour design for manufacturability (DFM) analysis, signal integrity simulation, and rapid prototyping with 10K-unit batch delivery within 15 days.
