BF1204 Datasheet PDF - NXP

DESCRIPTION

●The BF1204 is a combination of two equal dual gate MOS-FET amplifiers with shared source and gate 2 leads. 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.

●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.

●APPLICATIONS

●•  Gain controlled low noise amplifiers for VHF and UHF applications with 3 to 9 V supply voltage, such as digital and analog television tuners and professional communications equipment.
