BLF6G20-180PN,112

Overview

The BLF6G20-180PN is a 180 W LDMOS power transistor designed for base station applications in the 1800 MHz to 2000 MHz frequency range. It operates with a drain-source voltage of 32 V and features an integrated ESD protection circuit. The device utilizes a flanged balanced ceramic package (SOT539A) with two mounting holes and four leads. Typical performance at Tcase = 25 °C includes a power gain of 18 dB, drain efficiency of 29.5%, and ACPR of -35 dBc under 2-carrier W-CDMA conditions. The thermal resistance from junction to case is 0.45 K/W.
