FEATURES
DESCRIPTION
The UPA821TF 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.
Low noise figures, high gain, and high current capability equate
to wide dynamic range and excellent linearity. The thinner
package style allows for higher density designs.
