BF1118WR - Silicon RF switches

Download the BF1118WR datasheet PDF. This datasheet also covers the BF1118 variant, as both devices belong to the same silicon rf switches family and are provided as variant models within a single manufacturer datasheet.

General Description

These switches are a combination of a depletion type Field-Effect Transistor (FET) and a band-switching diode.

The BF1118, BF1118R, BF1118W and BF1118WR are encapsulated in the SOT143B, SOT143R, SOT343N and SOT343R respectively.

Key Features

  • Specially designed for low loss RF switching up to 1 GHz 1.3.

BF1118; BF1118R; BF1118W; BF1118WR Silicon RF switches Rev. 3 — 14 November 2014 Product data sheet 1. Product profile 1.1 General description These switches are a combination of a depletion type Field-Effect Transistor (FET) and a band-switching diode. The BF1118, BF1118R, BF1118W and BF1118WR are encapsulated in the SOT143B, SOT143R, SOT343N and SOT343R respectively. The low loss and high isolation capabilities of these devices provide excellent RF switching functions. The gate of the MOSFET can be isolated from ground with the diode, resulting in low losses. Integrated diodes between gate and source and between gate and drain protect against excessive input voltage surges. 1.2 Features and benefits  Specially designed for low loss RF switching up to 1 GHz 1.
