Digital DC-DC converter for RF power amplifier applications
Flex Power Modules has launched the BMR685, the first digital DC-DC converter for RF power amplifiers in the half-brick form factor that can offer continuous output power of up to 1300W.
With telecoms infrastructure shifting to 5G, the RFPA is becoming more power-hungry, and RF power amplifier designers move from LDMOS to GaN transistors. Overall, there’s a demand for highly efficient DC-DC converters to provide the power needed in a compact package. The device’s power-handling abilities make it ideal for these high-power RF power amplifier applications, for both LDMOS and GAN requiring a 50V rail.
