New IDEV Technology Boosts RFpower Terformance up to 1.4 kW

Combining high load mismatch capability with a high power density, this new LDMOS

transistor family is well suited for RF power amplifiers where they can be used as well as in HF & VHF communications, FM & TV Broadcasting, ISM and Avionics & Radar systems.

In addition to ST's recently introduced IDDE & IDCH 28/32V product portfolio, this new IDEV 50V LDMOS technology expands the range of applications that ST can address, giving power RF designers a competitive edge for cost-efficient solutions in addition to superior performance.
