BLF7G22LS-200,118

Overview

The BLF7G22LS-200,118 is a 200 W LDMOS power transistor designed for base station applications in the 2110 MHz to 2170 MHz frequency range. It operates with a drain-source voltage of 28 V and a quiescent current of 1620 mA. The device delivers an average output power of 55 W with a typical power gain of 18.5 dB and a drain efficiency of 31% under two-carrier W-CDMA conditions. Key electrical characteristics include a drain-source breakdown voltage of 65 V, a gate-source threshold voltage ranging from 1.5 V to 2.3 V, and a forward transconductance of 18.9 S. The thermal resistance from junction to case is typically 0.26 K/W.
