The BF1216 is a combination of two dual gate MOSFET amplifiers with shared source
and gate2 leads.
The source and substrate are interconnected. Internal bias circuits enable DC stabilization
and very good cross modulation performance d uring AGC. Integrated diod es between the
gates and source protect against excessive input voltage surges. The transistor is
available as a SOT363 micro-miniature plastic package.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.
1.2Features and benefits
Two low noise gain controlled amplifiers in a single package; both with a partly
integrated bias
Superior cross modulation performance during AGC
High forward transfer admittance
High forward transfer admittance to input capacitance ratio
1.3Applications
Gain controlled low noise amplifiers for VHF and UHF applications running on a 5 V
supply voltage
digital and an alog television tuners
professional communication equipment
