BLF7G15LS-200,112

Overview

The BLF7G15LS-200 is a 200 W LDMOS power transistor designed for base station applications in the 1450 MHz to 1550 MHz frequency range. It operates with a drain-source voltage of 28 V and a quiescent current of 1600 mA, delivering an average output power of 50 W with a typical power gain of 19.5 dB and drain efficiency of 29% under two-carrier W-CDMA conditions. The device features a maximum drain-source breakdown voltage of 65 V and a thermal resistance from junction to case of 0.30 K/W. It utilizes an earless flanged ceramic package (SOT 502B) with two leads.
