  • Abstract
    A GaAs MMIC active cold load for a wearable microwave radiometer is presented. A design procedure capable of achieving a minimum noise temperature at a specific bias point is described. A measured equivalent noise temperature of less than 90 K from 1.3 GHz to 1.5 GHz while maintaining an input return loss greater than 28 dB is demonstrated.
