Product Description
Functional Diagram
GND
The SCG015 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT is
able to achieve performance over a broad range with +41
dBm OIP3 and +24 dBm of compressed 1dB power and is
housed in a lead-free/green/RoHS-compliant SOT-89 SMT
package. All devices are 100% RF and DC tested.
• 1800 – 2500 MHz
• +24 dBm P1dB

• +40 dBm OIP3
• 15 dB Gain
• 5 dB Noise Figure
• Single Positive Supply (+8V)
The product is targeted for use as a gain block/driver
amplifier for various current and next generation wireless
technologies such as CDMA, CDMA2000, and W-CDMA,
where high linearity and medium power is required. In
addition, the SCG015 will work for numerous other
applications within the 1800 to 2500 MHz frequency range.

1. Test conditions unless otherwise noted: 25°C, Vsupply = +8 V, in tuned application circuit with
Rbias = 30 Ω.
2. 3OIP measured with two tones at an output power of +9 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
