Abstract :
A collaboration has been underway for the last several years to develop an L-band multipixel phased array feed for the Green Bank Telescope. These efforts will culminate in the deployment of a new wide-field observing instrument, Focal L-band Array for the GBT (FLAG).We report on progress on the cryogenic front end receiver system and real-time digital signal processing back end.
