BLF8G20LS-230VJ

Overview

The BLF8G20LS-230V is a 230 W LDMOS power transistor designed for base station applications in the 1800 MHz to 2000 MHz frequency range. It features improved video bandwidth and low memory effects for excellent pre-distortability. The device operates at a drain-source voltage of 65 V maximum, with typical performance measured at 28 V. In a common source class-AB test circuit at Tcase = 25 °C, it delivers an average output power of 55 W with a power gain of 18 dB and a drain efficiency of 31.7% under 2-carrier W-CDMA conditions. The thermal resistance from junction to case is typically 0.27 K/W.
