Application Solutions

Dapu provides comprehensive timing solutions for GPS and GNSS applications. The GPS timing solution includes high-stability TCXOs (±0.5ppm) for fast satellite acquisition, GPS SAW filters for excellent signal selectivity, and LNAs for low-noise signal amplification. These components work together to provide reliable GPS reception in challenging environments. The solution supports GPS L1, GLONASS, BeiDou, and Galileo systems. Dapu also offers reference designs and application notes for GPS receiver design. As an authorized distributor, we provide technical support for GPS timing design including frequency selection, filter matching, and sensitivity optimization.

Contact our FAE team for GPS timing solution recommendations and design support.

Designing a timing solution for telecommunications requires careful component selection. For telecom applications, Dapu offers VCXOs with appropriate pull ranges for synchronization, high-stability TCXOs for reference clocks, and crystal oscillators for general timing. The key considerations include frequency accuracy requirements (typically ±0.1-4.6ppm for telecom), temperature range (-40°C to +85°C industrial grade), phase noise specifications, and holdover requirements. Dapu provides reference designs for SDH/SONET, LTE base stations, and network synchronization. Our FAE team can assist with PLL design, loop filter optimization, and jitter analysis for your specific telecom application.

Dapu provides complete RF front-end solutions including SAW filters for frequency selection, low-noise amplifiers (LNAs) for signal amplification, and RF switches for antenna diversity. These components can be combined to create receive chains for various wireless standards including cellular (2G/3G/4G/5G), WiFi, Bluetooth, GPS, and ISM band applications. The solution approach involves selecting appropriate filter bandwidth, LNA gain and noise figure, and matching components for optimal performance. Dapu offers reference designs for common RF architectures and can provide guidance on matching, layout, and interference mitigation.

Yes, Dapu offers customization services for timing products to meet specific application requirements. Customization options include custom frequencies not in the standard catalog, special stability grades, modified temperature ranges, specific package requirements, and custom RF filter frequencies and bandwidths. Custom products typically require minimum order quantities and have longer lead times (8-12 weeks). As an authorized distributor, we can coordinate custom product development with Dapu factory, provide samples for qualification, and manage production scheduling. Contact our sales team to discuss your custom timing requirements and feasibility.
