This attenuator has an LSB of 10 dB. The AA103-72 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include cellular radio, wireless data, and wireless local loop gain level control circuits. 0.037 (0.95 mm) REF. 0.012 (0.30 mm) TYP. 0.024 (0.61 mm) 0.004 (0.10 mm) 0.122 (3.10 mm) 0.106 (2.70 mm) 0.0104 (0.26 mm) 0.0035 (0.09 mm) MIN.
