The µPA834TF is a low noise amplifier that can be used in the VHF band to UHF band. It has two different built-in transistors (Q1 and Q2) for low noise amplification.
The NEC uPA834TF is a silicon epitaxial NPN transistor offered in a 6‑pin thin‑type small mini‑mold package. It contains two distinct on‑chip transistors (Q1 and Q2) optimized for low‑noise amplification from VHF to UHF frequencies. The document provides detailed electrical characteristics, absolute maximum ratings, typical performance curves and S‑parameter measurements for both transistors.
Key sections include package drawings, ordering information, absolute maximum ratings such as collector‑to‑base voltage and power dissipation, electrical parameters like DC current gain and noise figure, and extensive S‑parameter tables for various bias conditions. Legal and safety notices conclude the sheet.
