Description
The SCG002B is a high reliability, high linearity, low cost broadband amplifier, optimized for commercial communications.
The device is manufactured using in-house developed, advanced Indium Gallium Phosphide Heterojunction Bipolar Transistor
(InGaP HBT) technology and is designed for use as a 50 Ohm gain block. The amplifier features excellent VSWR, low noise
figure and highly linear performance. Typical OIP3 is +29dBm at 1000MHz. The SCG002B operates from a single voltage
supply and requires only two DC-blocking capacitors, a bias resistor and an inductor for operation. The device is ideal for
wireless applications and is available in a low cost, surface-mountable SOT-89 packages. The SCG002B is designed in the
Darlington configuration with direct feed back. Its operation frequency at low end is limited only by the dc blocking capacitor
and the RF choke inductor (large values are required in both cases).
