                    BF1108; BF1108R
                    Silicon RF switches
                    Rev. 04 -- 29 May 2008                                                     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 in an SOT143B (BF1108) or SOT143R (BF1108R) package. 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.

CAUTION
                     This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
                     during transport and handling.
