1. Collector (Q1)
2. Emitter (Q1)
3. Collector (Q2)
4. Base (Q2)
Pin 1 is the lower left most pin as
the package lettering is oriented
and read left to right.
TheUPA831TFhastwodifferentbuilt-intransistorsforlowcost
amplifierandoscillatorapplicationsintheVHF/UHFband. 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.
