Vehicular Antenna Systems

SDSX's automotive-grade low-noise amplifiers (LNA) form the core of next-generation vehicle reception systems, enabling precise signal acquisition across diverse frequency bands—including legacy AM/FM analog radio, GPS navigation, digital broadcasting (DAB/DVB-T), Bluetooth® connectivity, satellite services (SDARS, e.g., SiriusXM), 4G/5G cellular networks, and V2X communications (Car2Car/Car2X).   Engineered to AEC-Q102 Grade 1 standards (-40°C to +125°C), our LNAs deliver critical performance advantages: ultra-wide bandwidth (DC-6 GHz), high gain (32 dB typical @ 2.4 GHz), and industry-leading low noise figure (as low as 0.8 dB).   These characteristics ensure seamless integration into multi-antenna architectures while supporting complex signal environments with uncompromised reliability.

The rapid emergence of low-altitude economies has propelled drone technology into widespread deployment across logistics delivery, security surveillance, and geospatial mapping, while simultaneously driving critical demand for counter-UAS systems to ensure secure and stable airspace management.    SDSX capitalizes on its profound RF communications expertise to deliver high-performance RF front-end solutions that enhance drone communication reliability.

SDSX develops high-bandwidth, high-gain, low-noise figure LNAs based on GaAs pHEMT technology;  high-linearity, high-efficiency PAs based on GaAs HBT technology;  and high-power, high-bandwidth, high-efficiency PAs based on GaN HEMT technology.  These solutions feature extremely broad application scenarios, particularly in wireless infrastructure, including:

• 4G/5G macro base stations

• 5G Sub-6GHz Massive MIMO base stations

• 5G mmWave base stations

• Microcells

• Indoor small cells

• Microwave point-to-point systems
