BF1212 Datasheet - NXP

BF1212 N-channel dual-gate MOS-FETs

Enhancement type N-channel field-effect transistor with source and substrate interconnected. Integrated diodes between gates and source protect against excessive input voltage surges. The BF1212, BF1212R and BF1212WR are encapsulated in the SOT143B, SOT143R and SOT343R plastic packages respectively..

BF1212 Features

* Short channel transistor with high forward transfer admittance to input capacitance ratio

* Low noise gain controlled amplifier

* Excellent low frequency noise performance

* Partly internal self-biasing circuit to ensure good cross-modulation performance during AGC
