BLF6G21-10G,112

Overview

The BLF6G21-10G is a 10 W LDMOS power transistor designed for base station applications across the HF to 2200 MHz frequency range. It operates at a supply voltage of 28 V with a drain-source breakdown voltage of 65 V and a maximum junction temperature of 225 °C. In typical 1-carrier W-CDMA mode, it delivers 2 W average output power with 19.3 dB gain and 31% efficiency. For 2-carrier W-CDMA, it provides 0.7 W output power with 18.5 dB gain and 15% efficiency. The device features integrated ESD protection and requires no internal matching for broadband operation.
