| DATA SHEET AA113-310: GaAs IC 6 Bit Digital Attenuator with Driver 0.5 dB LSB Positive Control DC-1 GHz Features QFN 5 x 5 (-310) 0.197 (5.00 mm) BSC Pin 1 Indicator 32 1 Attenuation 0.5 dB steps to 31.5 dB with high accuracy Single positive control for each bit Low DC power consumption CMOS integrated silicon driver Designed for use at IF frequencies 0.039 (1.00 mm) Max. 0.187 (4.75 mm) BSC 0.197 (5.00 mm) BSC 12 Max. 0.001 (0.025 mm) 0.187 (4.75 mm) BSC Seating Plane Description The AA113-310 is a 6 bit, single positive control GaAs IC FET digital attenuator with driver. It is particularly suited at IF frequencies where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data, broadband and wireless local loop gain control circuits. 0.122 (3.10 mm) 0.006 (0.15 mm) 0.122 (3.10 mm) 0.006 (0.15 mm) 32 1 0.138 (3.50 mm) Ref. 0.019 (0.50 mm) BSC 0.138 (3.50 mm) Ref.
