Wideband LDMOS transistors address broadcast, ISM applications
RF power amplifiers from Ampleon now include the 32V-rated BLP15M9Sxxx and the 50V-rated BLP15H9Sxxx devices.
Both families are based on the company’s 9th generation LDMOS and high voltage LDMOS technologies respectively and support frequencies of up to 2GHz. They are capable of both continuous wave (CW) and pulsed signal operation, with elevated levels of stability, says Ampleon.
The BLP15MSxxx family comprises dedicated devices offering 100, 70 and 30W and the BLP15H9Sxxx family supports devices delivering 100, 30 and 10W. The BLP15M9Sxxx devices will deliver efficiencies of around 75 per cent and with the BLP15H9Sxxx devices typically attaining +65 per cent.
Applications span particle accelerators and plasma generators through to MRI equipment, industrial heating systems, radar implementations and broadcast equipment.
Ampleon’s BLP15M9Sxxx and BLP15H9Sxxx LDMOS amplifiers are supplied in a choice of robust packages, namely compact SOT1482-1 (straight lead) and SOT1483-1 (Gull wing) format packages. The plastic packaging helps to ensure thermal performance is maintained, while also keeping unit costs down, notes Ampleon. Dual-side electro-static discharge (ESD) protection is incorporated into each device.
