BF1214 - NXP Semiconductors

BF1214 Dual N-channel dual gate MOSFET

The BF1214 is a combination of two dual gate MOSFET amplifiers with shared source and gate2 leads. 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 has.
