General description

The BF1206F is a combination of two different dual gate MOSFET amplifiers with shared source and gate2 leads.

The source and substrate are interconnected. Internal bias circuits enable Direct Current (DC) stabilization and a very good cross-modulation performance during Automatic Gain Control (AGC). Integrated diodes between the gates and source protect against excessive input voltage surges. The transistor is encapsulated in a SOT666 micro-miniature plastic package.

Features

■ Two low noise gain controlled amplifiers in a single package

■ Superior cross-modulation performance during AGC

■ High forward transfer admittance

■ High forward transfer admittance to input capacitance ratio

■ Suited for 3 volt applications

Applications

■ Gain controlled low noise amplifiers for Very High Frequency (VHF) and Ultra High Frequency (UHF) applications with 3 V supply voltage, such as digital and analog television tuners
