Enhancement type field-effect transistors. The transistors BF904AWR consist of an amplifier MOS-FET with source and substrate interconnected and an internal bias circuit to ensure good cross-modulation performance during AGC.
The BF904A, BF904AR and BF904AWR are encapsulated in the SOT143B, SOT143R and SOT343R plastic packages respectively.
