Optimization
Performance and optimization
Reliable wireless performance requires optimization from the RF architecture level all the way to the final integrated product. Sasken utilizes circuit-level, block-level, and system-level simulations together with laboratory measurements to verify performance throughout development.
Focus is placed on receiver sensitivity, transmitter efficiency, link budget performance, multi-radio coexistence, and interference mitigation. Because RF performance depends strongly on PCB layout, antenna behavior, grounding strategy, shielding, and mechanical structures, our RF engineers work closely with antenna, electronics, and layout specialists to optimize complete wireless systems.
Key optimization areas include:
- RF circuit, block-level, and system-level simulations
- Receiver sensitivity and transmitter performance optimization
- Multi-radio coexistence and interference analysis
- EMC-aware RF design and verification
By identifying performance limitations early, we help customers reduce redesign cycles and improve overall wireless system reliability.
