- This memo discusses design considerations for the new Analog Receivers (ARXs), focusing on the choice of amplifiers. The main concern is avoiding intermodulation from the very strong RFI that accompanies the signal received by the ARX from the antenna. The strongest RFI is outside observing band, but there is little filtering ahead of the ARX. Measurements have shown that the total RFI power is nearly 1000 times larger than the total power in the observing band.
