DESCRIPTION
The UPA831TF has two different built-in transistors for low cost
amplifier and oscillator applications in the VHF/UHF band. Low
noise figures, high gain, high current capability, and medium
output give this device high dynamic range with excellent
linearity for two-stage amplifiers. This device is also ideally
suited for use in a VCO/buffer amplifier application. The
thinner package style allows for higher density designs.

1. Collector (Q1)
2. Emitter (Q1)
3. Collector (Q2)
4. Base (Q2)
5. Emitter (Q2)
6. Base (Q1)
Note:
Pin 1 is the lower left most pin as
the package lettering is oriented
and read left to right.
