BF1102 General Description
The BF1102 is a combination of two equal dual gate MOS-FETs with shared source and gate 2 leads.
The source and substrate are interconnected. An internal bias circuit enables DC stabilization and a very good cross-modulation performance at 5 V supply voltage. Integrated diodes between the gates and source protect against excessive input voltage surges. The transistor has a SOT363 micro-miniature plastic package.
BF1102 Features
• Two low noise gain controlled amplifiers in a single package
• Specially designed for 5 V applications
• Superior cross-modulation performance during AGC
• High forward transfer admittance
• High forward transfer admittance to input capacitance ratio.
BF1102 Typical Application
• Gain controlled low noise amplifier for VHF and UHF applications such as television tuners and professional communications equipment.
