R & D Team

1) Talented team consisting of 60 engineers
2) Chief engineers with 20+ years' experience in designing RF/MW SSPA
3) Design with state-of-the-art GaN, GaAs, LDMOS and bipolar device technologies

R&D has always been put into a strategic position by Keylink.

In order to apply the latest technologies to products, Keylink maintains and upgrades all R&D hardware and software facilities annually. We encourage and support the further education of our employees and have carried out a plan for talents development. We also send engineers to communicate with domestic and foreign universities, research institutes, etc. Meanwhile, every year we participate in various large microwave exhibitions such as IMS, EuMW, etc.

In design stage, lots of CAD tools are used by us, for instance, electromagnetic simulation software, thermal simulation software, structural simulation software.

Keylink's high power combiners can reach over 90% efficiency and 100kW combined power. Keylink's digital pre-distortion platform and RF pre­distortion technology can greatly improve communication quality, allowing power amplifiers to maintain over 35% efficiency with EVM characteristics less than 2% at 40MHz signal bandwidth. MCM technology and the selection of high-efficiency GaN components have also improved our miniaturization technology.
