BLF871S - UHF power LDMOS transistor

Download the BLF871S datasheet PDF. This datasheet also covers the BLF871 variant, as both devices belong to the same uhf power ldmos transistor family and are provided as variant models within a single manufacturer datasheet.

Description

A 100 W LDMOS RF power transistor for broadcast transmitter applications and industrial applications.

The transistor can deliver 100 W broadband from HF to 1 GHz.

The excellent ruggedness and broadband performance of this device makes it ideal for digital transmitter applications.

Features

  • 2-tone performance at 860 MHz, a drain-source voltage VDS of 40 V and a quiescent drain current IDq = 0.5 A: ‹ Peak envelope power load power = 100 W ‹ Power gain = 21 dB ‹ Drain efficiency = 47 % ‹ Third order intermodulation distortion =.
  • 35 dBc.
  • DVB performance at 858 MHz, a drain-source voltage VDS of 40 V and a quiescent drain current IDq = 0.5 A: ‹ Average output power = 24 W ‹ Power gain = 22 dB ‹ Drain efficiency = 33 % ‹ Third order intermodulation distortion.
