Description

The objective of this activity is to realise an active breadboard for integration with an existing feed horn-array, populated with COTS LNA MMIC’s, waveguide interfaces, and SMP- and DC-connectors consisting of 7 RF-channels in total. The frequency band is 35.5-36 GHz. Each channel has one LNA that can be switched on or off via an external control line, and a coupler for calibration purposes. The complete circuitry is noise optimised, and representative of a front-end for the later flight implementation. The knowledge on noise figure to be gained is highly relevant for all Ka-band instruments as e.g. ocean wide swath altimeter, SAR for cryosphere research and high resolution 3D imaging of the earth environment.
