QPA1008 2.73.8 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 Lead-free and RoHS compliant. Small Signal Gain: 28 dB Input Return Loss: 16 dB Output Return Loss: 15 dB 32dB Attenuation Range P1dB: 31dBm Large Signal Gain: 26 dB P1dB PAE: 35 % Bias Switching Speed: 20 nS Bias: V = 6 V, I = 400 mA CC CQ Package Dimensions: 5.0 x 5.0 x 0.82 mm Performance is typical across frequency.
