摘要：

This direct detection W-Band radiometer front end module for real-time imaging employs a monolithic microwave integrated circuit (MMIC) low noise amplifier (LNA), a highly sensitive detector and a video amplifier. The detector has a responsivity of 1000 mV/mW over a 21 GHz bandwidth. The compact module (measuring 13 X 20 X 56 mm) achieves a temperature sensitivity of 0.83 K with an integration time of 2.3 MS over a 22 GHz bandwidth. It is a candidate for large imaging array applications.
