BLF8G22LS-270J

Overview

The BLF8G22LS-270 is a 270 W LDMOS power transistor designed for base station applications in the 2110 MHz to 2170 MHz frequency range. It operates at a drain-source voltage of 28 V with a quiescent current of 2400 mA. The device provides a typical power gain of 17.7 dB and a drain efficiency of 30% under two-carrier W-CDMA test conditions. It features an earless flanged ceramic package (SOT502B) with a junction-to-case thermal resistance of 0.26 K/W.
