PRELIMINARY DATA SHEET
NPN SILICON EPITAXIAL TWIN TRANSISTOR UPA826TF
FEATURES
• LOW NOISE AND HIGH GAIN
• OPERABLE AT LOW VOLTAGE
• SMALL FEEDBACK CAPACITANCE:
Cre = 0.4 pF TYP
• SMALL PACKAGE STYLE:
2 NE685 die in a 2 mm x 1.25 mm x 0.6 mm package
DESCRIPTION
The UPA826TF has two built-in low-voltage transistors which
are designed for low-noise amplification in the VHF to UHF
band. The two die are chosen from adjacent locations on the
wafer. These features combined with the pin configuration
make this device ideal for balanced or mirrored applications.
This device is suitable for very low voltage/low current, and low
noise applications. The thinner package style allows for higher
density designs.
