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.
