The AA103-72 from Alpha Components is a 1 bit GaAs IC FET digital attenuator designed for gain level control circuits in applications such as cellular radio, wireless data, and wireless local loop.
This attenuator features a 10 dB attenuation cutback and operates with a single positive 3V control voltage. It offers low insertion loss, with values ranging from 0.3 dB at DC-0.5 GHz to 0.7 dB at DC-2.5 GHz. The attenuation accuracy is specified as ± (0.25 + 3% of Attenuation Setting in dB) up to 1.0 GHz and ± (0.4 + 5% of Attenuation Setting in dB) up to 2.5 GHz.
Electrical specifications include a VSWR (I/O) of 1.2:1 to 1.4:1 across the DC-2.5 GHz frequency range. Switching characteristics show a rise/fall time of 150 ns and an on/off time of 300 ns. The device can handle input power for 1 dB compression of +20 dBm at +3V and +26 dBm at +5V. Intermodulation intercept point (IP3) is +41 dBm at +3V and +45 dBm at +5V.
The AA103-72 is housed in a low-cost SOT-5 plastic package, suitable for surface mount applications. External DC blocking capacitors, a bypass capacitor, and biasing resistors are required for positive voltage operation.
