   Sammanfattning : This thesis deals with the design and performance of some novel devices for an imaging receiver, operating in the frequency band centered at 100 GHz, to be used in radio astronomy research. The emphasis is given on simple, small and reliable devices in order to reduce the complexity of an already complex receiver. LÄS MER
