The QPA1008 is a two-stage variable gain amplifier for S-band applications from 2.7 to 3.8 GHz.
It includes a 30 dB analogue attenuator and resistively coupled power detector at the output for circuits requiring power monitoring.
<20 nS bias switching for quick turn-on/turn-off operation improves system sensitivity in commercial and military radar, communications systems and test & measurement applications.
