Receiver for 94GHz Phased-Array-Type Weather Radar

Model No. RAD73

Used for the checkup of the cloud radar mounted on satellite EarthCARE
(Earth Clouds, Aerosols, and Radiation Explorer).
Configurable array antenna (e.g., zigzag confi guration)
Phased array receiver for a Millimeter-Wave (94 GHz band) weather radar.
The grating lobe of the electron scanning direction can be mitigated by changing the confi guration.
The gain and phase shifting are accurately adjusted for each RF receiver module so that each RF module does not incur a phase shift.
Therefore, the phase shifter is installed for each fan beam (linear array).
