	RFtronics LLC Corona, CA 951-256-0409

RFtronics is a young engineering company which develops both turnkey and custom solutions for RF telecom equipment designers and manufacturers.

Currently, our product line includes high power couplers, splitters, and combiners between
20 MHz and 3 GHz.

We have a tight relationship with a local, ISO certified manufacturer with a 25 000 sq. ft. facility and more than 20 years experience in the RF/microwave design and manufacture. This gives us the best of both worlds, the agility of a small company and the production capabilities of a larger-sized, high-volume manufacture. RFtronics will usually deliver prototype quantities (less than 50pcs) directly and for larger orders the design will be transferred to our manufacturing partner.
