X-Band 256-Channel 2D Active Phased Array Antenna
A high-efficiency 16×16 active scanning matrix delivering ≥80 dBm EIRP. Engineered for precision tactical radar with sub-50µs beam handover and fully transparent RS422 baseband control.
Optimal EIRP Density
Generating a reliable EIRP of ≥ 80 dBm across the 9.2 to 9.8 GHz band, striking the perfect operational balance between detection range and power efficiency (≤ 235W).
Precision Steering
Achieves an angular pointing error of ≤ 0.15° within a ±20° scan range, critical for maintaining reliable target locking in complex fire-control networks.
Rapid Beam Handover
Engineered for highly dynamic tracking scenarios, this active array executes rapid beam handover sequences in ≤ 50 µs across its full scanning envelope.
Protocol Transparency
Fully documented Synchronous RS422 protocol allowing baseband engineers absolute control over the 256 internal phase shifters and real-time operational telemetry.
X-Band 256-Channel Active Phased Array
TOPOLOGY: 16×16 MATRIXThis high-performance system consists of 256 antenna elements intelligently distributed across an Antenna-in-Package (AiP) matrix. The architecture integrates a monopulse sum-and-difference network, power supply wave controller, and frequency synthesizer into a highly compact 60mm-thick chassis. Upon reception, the AiP matrix captures, amplifies, and applies precise phase and amplitude compensation to the incoming RF signals. The internal combiner network then synthesizes these signals into highly accurate spatial, azimuthal, and elevation beams.
Weighing strictly ≤ 3.5 kg, this 256-channel array represents the ideal payload "sweet spot" for mid-sized mobile platforms and advanced UAV installations. It delivers exceptional spatial resolution (5.8° Tx beamwidth) while capping max power consumption at 235W (20% duty cycle). The exposed synchronous RS422 protocol structure (J30J-15ZK interface) offers radar architects unparalleled backend control for complex integrations.
