Even the best amplifier will still add some noise to ... This is likely to happen if you live close to a transmitter. Attenuators can be used to decrease the incoming signal if it is too strong ...

PA consists of attenuator, 1-stage amplifier with tunable gain. Attenuator reduces output power by 1dB from 0 to 60 dB. The amplifier gain is adjustable in increments of 2 dB.

In the RF world, attenuators are a useful test and measurement tool. Variable units that can apply different levels of attenuation in discrete steps are even better. [DuWayne] made a 63 dB step ...
