From initial simulation to global dispatch, Kavveri controls every step of the RF product lifecycle. Our vertically integrated setup—spanning advanced design tools, rapid prototyping, automated manufacturing, and comprehensive testing—ensures superior quality, fast turnaround times, and full traceability. This gives our customers a strategic edge, especially in mission-critical deployments.
We use industry-standard electromagnetic design software such as CST Studio Suite, Keysight EMPro, and Advanced Design System (ADS) for antenna, filter, and system-level simulations. These tools allow us to model complex RF behavior, optimize for gain, isolation, impedance, and field coverage before a single prototype is built, saving weeks of costly iterations.
Our production facilities are equipped for high-volume manufacturing of both antennas and RF filters, supporting global OEM rollouts and defense programs. With automated machining, PCB assembly lines, and temperature-controlled testing chambers, we maintain high throughput while meeting ISO and MIL-STD quality requirements.
Kavveri operates multiple in-house testing environments:
This enables us to certify performance across a wide frequency range and usage environments before shipping.
Our products are designed and qualified to survive extreme mechanical, thermal, and environmental stress. Whether it’s vehicle-mounted antennas facing shock and vibration or space-bound hardware undergoing thermovac cycling, we ensure compliance with MIL-STD-810, DO-160, and other global ruggedization benchmarks.
We offer NPI programs with quick-turn engineering that allow customers to go from concept to field test in record time. Whether it’s for a defense tender, an aerospace proof of concept, or a telco pilot deployment, our agile development team can deliver working prototypes within weeks, often with multiple iterations to meet tight technical specs.
