Elevation Switching Module (GD0125)
Delivered ultra-fast, synchronized RF switching for mission-critical defence radar systems
Industry: Defence Communication Systems
Why Clients Choose GD:
Our PSU selected General Datum for this mission-critical project for our ability to deliver end-to-end embedded solutions under tight timelines. We brought together circuit design, high-speed multi-layer PCB layout, deterministic firmware, and custom GUI development within a single, cohesive team.
Our simulation-first approach, deep understanding of defence-grade requirements, and strong track record of first-pass success ensured the system met strict synchronization and reliability demands. Most importantly, we combined technical precision with rapid execution, making us a trusted partner for complex embedded systems.
Challenge:
Our client needed a highly reliable 32-channel RF switching control system capable of synchronizing 128 RF cards across multiple boards with deterministic timing under 200 microseconds — a critical requirement for real-time radar and communication platforms.
Our Solution:
General Datum designed and delivered a complete embedded hardware-firmware solution featuring four 8-layer circular control boards connected through an Ethernet hub. We handled end-to-end development: circuit design, high-speed PCB layout with controlled impedance routing, firmware with precise SPI and UDP protocols, and a custom GUI for seamless operation.
Key Results:
- Achieved synchronized 32-channel switching in \~200 microseconds
- Delivered full system (design + firmware + GUI + validation) in just 4 months
- Successfully met Class-2 performance standards for defence applications
- Ensured reliable operation through robust SPI control, TTL signalling, and EEPROM management
This project strengthened client’s radar and communication platforms with scalable, high-precision embedded control technology.
