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.

There was even room to add a micro USB plug for recharging the power supply. The two smaller digital attenuators [DuWayne] used are essentially breakout boards for the PE4302 digital RF attenuator ...

To check, remove the power from the amplifier and ... though the two work by different methods. While an amplifier provides gain, boosts the signal, an attenuator provides loss, reduces the ...
