A distributed low noise amplifier (DLNA) comprises at least a first amplifier part 30.1 providing a first path 36.1 form an input of the amplifier to an output of the amplifier and a second amplifier part 30.2 providing a second path 36.2 from the input to the output. Each of the first and second paths being associated with a respective and different change in phase. The difference being larger than degrees in a noise suppression band to cause a phase difference between noise generated by the amplifier arrangement propagating along the first and second paths and destructive interference of the noise before the output of the DLNA, thereby to suppress noise in the noise suppression band. The respective gains of the amplifier parts 30.1 to 30.n may decrease in a direction from the input of the amplifier to the output thereof.
