SCG002
HIGH LINEARITY BROADBAND AMPLIFIER
DC - 6000 MHz
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. T ypical 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).

1RFin
This pin has a nominal 50 ohm input impedance. It requires a DC blocking capacitor large
enough t o handle the lowest frequenc y used.
2, 4 Gnd The two ground c onnections should be dir ectly connec ted together to the ground plane on
the PCB. The ground connection al so serves as a heatsink.
3RFout
This pin has a nominal 50 ohm output impedance. It requires a DC bias of 45mA through a
series inductor and a resistor. A bypass capacitor ( 1.0 micro Farad) on the DC side of the
inductor is recommended for providing instantaneous current during a modulated RF signal.
Use a DC bl ocking capacitor on the output with similar requirements as the input side.

Reliability and Burn-In Test
EiC performs burn-in for selected lots on a regular basis to monitor and guarantee consistent product quality and reliabil-
ity . The burn-in process consists of pre-conditioning (JESD22-A1 13-B), pre and post RF tests, and bias life (JESD22-
A108-A).
The table is based on the following parameters and conditions:
Activation Energy: 1.85eV
Junction to Ambient Temperature Difference: +23oC
Confidence levels of 60% and 90% are used to calculate FIT (Failure In Time), for the nominal operating ambient tem-
perature at +25oC.
EiC will update the burn-in and cumulative FIT results periodically . Please check the website at www.eiccorp.com
