RF3L05150CB4

Overview

The RF3L05150CB4 is a 150 W, 28/32 V LDMOS FET designed for wide-band communication and ISM applications with frequencies from HF to 1 GHz. It can be used in class AB, B or C for all typical modulation formats. The device operates at 520 MHz with an output power of 150 W, gain of 23 dB, and efficiency of 60%. Absolute maximum ratings include a drain-source voltage of 90 V, gate-source voltage range of -8 to 10 V, and maximum junction temperature of 200 °C. Static characteristics feature a drain-source on-state resistance of 1 Ω and a threshold voltage of 2.5 V typ. Dynamic performance specifies a load mismatch VSWR of 20:1 at 150 W pulsed CW output power.
