Low noise figures, high gain, high current capability, and medium output give this device high dynamic range and 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. PIN CONNECTIONS 1. Collector (Q1) 2. Emitter (Q1) 3.
