描述 Description

Overview Archived content is no longer updated and is made available for historical reference only.
The BF1218 is a combination of two dual gate MOSFET amplifiers with shared source and gate2 leads and an integrated switch. The integrated switch is operated by the gate1 bias of amplifier B. The source and substrate are interconnected. Internal bias circuits enable DC stabilization and a very good cross modulation performance during Automatic Gain Control (AGC). Integrated diodes between the gates and source protect against excessive input voltage surges.The transistor has a SOT363 micro-miniature plastic package.
