CAUTION
1.1 General description
1.2 Features
1.3 Applications
The BF1205C is a combination of two dual gate MOS-FET amplifiers with shared source
and gate 2 leads and an integrated switch. The integrated switch is operated by the gate 1
bias of amplifier b.
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 has a SOT363 micro-miniature plastic package.
