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.
