ABSTRACT:
A highly integrated radiometer sensor cell includes a base having opposing surfaces with one surface adapted for surface mounting on a board. A radio frequency (RF) feed receives RF signals and at least one MMIC is operatively connected to the RF feed and receives the RF signals from the RF feed. This MMIC can include at least one quadrature hybrid, a low noise amplifier (LNA) connected thereto, and a detector circuit for producing a detected signal for further radiometer processing.
