Product Description

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.

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.

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.
