                 BF1215
                 Dual N-channel dual gate MOSFET
                 Rev. 01 -- 6 May 2010                                                  Product data sheet




1. Product profile

          1.1 General description
              The BF1215 is a combination of two dual gate MOSFET amplifiers with shared source
              lead, shared gate2 lead and an integrated switch.

              The source and substrate are interconnected. Internal bias circuits enable DC stabilization
              and a very good cross modulation performance during AGC. Integrated diodes between
              the gates and source protect against excessive input voltage surges. The transistor is
              availiable as a SOT363 micro-miniature plastic package.

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




          1.2 Features and benefits
                 Two low noise gain controlled amplifiers in a single package; one with full internal bias
                 and one with partial internal bias
                 Superior cross modulation performance during AGC
                 High forward transfer admittance to input capacitance ratio
                 Suitable for VHF and UHF applications: both amplifiers are optimized for VHF
                 applications.
                 Internal switch reduces external components

          1.3 Applications
                 Gain controlled low noise amplifiers for VHF and UHF applications with a 5 V supply
                    Digital and analog television tuners
