FEATURES
 Two low noise gain controlled amplifiers in a single
 Internal switch reduces the number of external
 Superior cross-modulation performance during AGC
 High forward transfer admittance
 High forward transfer admittance to input capacitance
APPLICATIONS
 Gain controlled low noise amplifiers for VHF and UHF
DESCRIPTION
The BF1205 is a combination of two equal 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 is encapsulated in SOT363
micro-miniature plastic package.
