| Description: | The front end PCB of the HBA antenna should work in an outdoor environment. The influence of temperature on the performance criteria like: current, gain and phase is analysed from -20C to +40C in a climate chamber. The current, gain and phase of the front end PCB is in a second test also measured during several days at a continuous temperature of 25C. This test should confirm the phase and gain stability of the electronics. These tests will be repeated with more PCBs to confirm the design. |
