Product Details
Product Overview
Engineers deploying terminals for modern low-Earth orbit networks often grapple with standard antenna arrays that exhibit high power consumption, thermal management issues, and slow electronic steering during critical satellite passes. The SDL-1024 overcomes these hardware limits through optimized chip-level integration that delivers a high G/T ratio of 8.5 dB/K at 12.5 GHz and an EIRP of 43 dBW at 14.5 GHz. This architecture ensures high-speed data throughput and robust link margins without demanding massive power infrastructure. Capable of executing wide-angle beam steering up to a 65° off-axis elevation angle and a full 360° azimuth adjustment, this LEO satellite tracking component provides terminal manufacturers with a reliable subsystem that maintains solid links even under severe extreme environmental temperatures from -40°C to +55°C.

FAQ
- Why are dual GPS and IMU modules integrated directly onto the SDL-1024 panel?
- Low-Earth orbit (LEO) satellites travel at high speeds across the sky, requiring the antenna beam to track and transition from one satellite to the next without dropping packets. By embedding dual GPS modules and a high-accuracy Inertial Measurement Unit (IMU) directly into the hardware layer, the panel gains immediate, real-time spatial orientation data. This allows the tracking algorithms to steer the beam with sub-degree accuracy, compensating for the physical movement or vibration of the host vehicle instantly.
- How does the polarization configuration function on the SDL-1024 for transmit and receive paths?
- This antenna panel utilizes a high-definition frequency division duplexing (HD-FDD) architecture with isolated polarization states to prevent signal interference. The receive path (10.7~12.75GHz) is configured for Right-Hand Circular Polarization (RHCP), while the transmit path (13.75~14.5GHz) utilizes Left-Hand Circular Polarization (LHCP). This design ensures maximum cross-polarization isolation, protecting weak incoming satellite signals from being degraded by the system’s own transmit power.
- What are the typical power and mounting requirements for integrating this subsystem?
- The Ku-band satellite antenna is designed for straightforward integration into compact commercial or tactical terminals, requiring only a standard 12V DC power supply. It features an exceptionally low power profile, consuming less than 65W when in receive-only mode and keeping consumption under 100W when transmitting at full power. Its flat 350mm x 500mm dimensions make it ideal for low-profile roof mounts or portable terminal assemblies that face strict size and power budgets.
