QPA1008  
2.7ꢀ–ꢀ3.8 GHz Variable Gain Driver Amplifier  
Product Description  
Qorvo's QPA1008 is an S-band two stage variable gain  
driver amplifier in a 5x5 mm QFN. The QPA1008 operates  
from 2.7 to 3.8 GHz and provides 31dBm of P1dB output  
power with 26 dB of large signal gain and greater than  
30% PAE. The QPA1008 includes a 30 dB attenuator at  
the input, and a simple resistively coupled (~-20 dB  
coupling) power sampler detector at the output. The  
amplifier has a fast bias control switch for quick turn on  
and off operation.  
Product Features  
Frequency Range: 2.7 – 3.8 GHz  
Small Signal Gain: 28 dB  
Input Return Loss: 16 dB  
Output Return Loss: 15 dB  
32dB Attenuation Range  
P1dB: 31dBm  
Lead-free and RoHS compliant.  
Evaluation Boards are available upon request.  
Large Signal Gain: 26 dB  
P1dB PAE: 35 %  
Bias Switching Speed: 20 nS  
Bias: VCC = 6 V, ICQ = 400 mA  
Package Dimensions: 5.0 x 5.0 x 0.82 mm  
Performance is typical across frequency. Please  
reference electrical specification table and data plots for  
more details.
