Delivering cutting-edge solutions in Radio Frequency engineering, from conceptual design to certified testing.
In-Depth Service Descriptions
Antenna Design & Optimization
We provide custom antenna solutions meticulously tailored to your specific frequency bands (ISM, Cellular, Wi-Fi, BT, GPS) and stringent form factor requirements. Our process includes full 3D simulation, matching circuit design, and optimization to ensure maximum radiation efficiency and reliability, even in complex embedded environments. This comprehensive approach covers everything from chip antennas and patch antennas to custom PCB-integrated designs, ensuring your product's wireless performance is industry-leading. We specialize in reducing the physical footprint of the antenna while maintaining high gain and bandwidth.
Our team utilizes industry-leading EM simulation software to predict and optimize performance before any physical prototypes are built, saving significant time and cost in the development cycle. We handle all aspects of the feed network design, including baluns and impedance matching circuits, to guarantee optimal power transfer from the radio module to the antenna element.
Final testing is conducted in a professional anechoic chamber to provide certified data on all radiation characteristics.
Project Examples & Capabilities
Anechoic Chamber Testing
Anechoic Chamber Testing Details: We conduct comprehensive over-the-air (OTA) and radiation pattern measurements in a state-of-the-art shielded, reflection-free environment. This is critical for accurate performance verification, allowing us to generate reliable data for TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity) metrics. We provide full 3D radiation pattern visualization, ensuring compliance with global standards.
Our chamber supports testing across a wide range of frequencies and standards, including 5G, LTE, Wi-Fi 6/7, and various ISM bands. The precision of our equipment guarantees accurate measurement of power output and receiver sensitivity, which are vital for product quality and regulatory approval.
Testing Examples
VSWR & Gain Measurement
VSWR & Gain Measurement Details: Precise testing of critical antenna parameters including VSWR (Voltage Standing Wave Ratio), gain, efficiency, and impedance matching using high-precision Vector Network Analyzers (VNAs) and spectrum analyzers. We provide detailed S-parameter measurements (S11, S21) and bandwidth performance reports.
Understanding and optimizing VSWR is fundamental to maximizing the link budget and minimizing power reflection. Our reports give you clear, actionable data to refine your matching network for peak performance, ensuring minimal signal loss between the radio front-end and the antenna element.
Measurement Examples
RF Bench Level Testing & Debug
RF Bench Level Testing & Debug Details: We handle early-stage RF circuit verification, component characterization, and debugging using advanced test equipment like signal generators, spectrum analyzers, and oscilloscopes. This is crucial for identifying and mitigating issues like phase noise, spurious emissions, intermodulation distortion, and ensuring power amplifier linearity under various load conditions.
Our bench services provide quick turnaround time for design verification, ensuring your design is robust before moving to expensive chamber testing. We focus on diagnosing and fixing issues related to power supply noise and unintended coupling within the board.
Testing Tools
High-Speed PCB Layout for RF
High-Speed PCB Layout for RF Details: Expert design and layout for high-frequency PCBs, focusing on controlled impedance traces (microstrip, stripline), proper ground plane stitching, power delivery network (PDN) integrity, and mitigation of cross-talk and EMI. We optimize component placement and routing using advanced simulation tools to minimize parasitic effects.
Correct layout is the foundation of a successful RF product. We ensure proper component isolation, thermal management, and adhere to strict design rules for high-frequency signal paths, preventing costly re-spins.
