DESCRIPTION
Enhancement type field-effect
transistors. The transistors 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.
