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 is encapsulated in a SOT363 micro-miniature plastic package.
