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 1.3 Applications Various RF switching applications such as: Passive loop through for VCR tuner Transceiver switching 1.4 Quick reference data Table 1.
