GND
The SCG002 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the SCG002 typically provides 21
dB of gain, +29 dBm Output IP3, and +15.5 dBm P1dB.

• +15.5 dBm P1dB at 1 GHz
• +29 dBm OIP3 at 1 GHz
• 21 dB Gain at 1 GHz
• 3.8 dB Noise Figure
The SCG002 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT process technology
and only requires DC-blocking capacitors, a bias resistor,
and an inductive RF choke for operation. The device is
ideal for wireless applications and is housed in a lead-
free/green/RoHS-compliant SOT-89 SMT package. All
devices are 100% RF and DC tested.

Applications
The broadband MMIC amplifier can be directly applied to
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, and W-CDMA. In addition,
the SCG002 will work for other various applications within
the DC to 6 GHz frequency range such as CATV and
mobile wireless.

1. Test conditions unless otherwise noted: 25 ºC, Supply Voltage = +5 V, Rbias = 24 Ω, 50 Ω system.
2. 3OIP measured with two tones at an output power of +2 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
