BF1102 NXP Semiconductors, BF1102 Datasheet - Page 2

• Manufacturer Part Number: BF1102
• Description: Enhancement type Field-Effect Transistor in a plastic SOT363 package
• Manufacturer: NXP Semiconductors

NXP Semiconductors
FEATURES
 Two low noise gain controlled amplifiers in a single
 Specially designed for 5 V applications
 Superior cross-modulation performance during AGC
 High forward transfer admittance
 High forward transfer admittance to input capacitance
APPLICATIONS
Gain controlled low noise amplifier for VHF and UHF
applications such as television tuners and professional
communications equipment.
DESCRIPTION
The BF1102 and BF1102R are both two equal dual gate
MOS-FETs which have a shared source pin and a shared
gate 2 pin. Both devices have interconnected source and
substrate; 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.
Both devices have a SOT363 micro-miniature plastic
package.
