General description

The BF1210 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 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; both with a partly integrated bias

■ 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 5 V supply voltage

◆ digital and analog television tuners

◆ professional communication equipment
