Ampleon Unveils LDMOS Transistors for Frequencies up to 2 GHz
The two new series of wideband devices support both continuous wave (CW) and pulsed signal operation at powers of up to 100 watts.
The BLP15M9Sxxx and the BLP15H9Sxxx series are rated at 32V and 50V, respectively. The former is based on Ampleon’s 9th generation LDMOS (laterally-diffused metal-oxide-semiconductor) technology while the latter employs the company’s high-voltage LDMOS technology process.

The BLP15MSxxx family is composed of devices offering 100, 70, and 30 watts and attain efficiencies of up to 78%. The BLP15H9Sxxx family includes semiconductors delivering 100W, 30W, and 10W and reach efficiencies of 65% or better. These new devices are part of a wide range of Ampleon 12, 32, and 50-volt broadband amplifiers.
The 50 Volt BLP15H9S Series
The three members of this series are LDMOS driver transistors aimed at applications in the frequency range from HF to 2 GHz. The units are the 10W BLP15H9S10, the 30W BLP15H9S30, and the 100W BLP15H9S100
For the BLP15H9S10 and the BLP15H9S30, Ampleon offers typical responses when testing for Pulsed RF and CW.
