Extremely Rugged 50 V LDMOS Devices Capture ISM and Broadcast Markets

During the last two and a half decades, VDMOS transistors have been the workhorses in many ISM and broadcast applications. Now, that era has come to an end due to continuous improvements in Ampleon’s 50 V LDMOS technology. The BLF18x-XR series of LDMOS devices enables superior reliability and lower system cost, while eliminating the need for hazardous substances associated with VDMOS packages. This new XR series has been specifically designed for RF energy applications in the industrial, scientific and medical (ISM) frequency bands, where ruggedness, stability and reliability are key drivers both in the market and in transistor design. The devices also enable high efficiency FM and VHF-TV broadcast transmitters with superior correctable linearity.
