This attenuator has an LSB of 1 dB and a total attenuation of 31 dB. The AA260-85 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include cellular radio, wireless data, wireless local loop and other gain level control circuits. 0.069 (1.75 mm) ±0.004 (0.10 mm) 0.283 (7.20 mm) ±0.012 (0.30 mm) 0.0256 0.078 (0.65 mm) (2.00 mm) BSC MAX. 0.010 (0.25 mm) 0.004 (0.090 mm) 8˚ MAX. 0.012 (0.30 mm) REF. 0.008 (0.20 mm) MAX. 0.002 (0.05 mm) MIN. 0.030 (0.75 mm) ±0.008 (0.10 mm) Electrical Specifications at -40°C to +85°C (0, -5 V) Parameter1 Insertion Loss Condition Frequency2 DC–0.5 GHz DC–1.0 GHz DC–2.0 GHz DC–1.0 GHz DC–1.8 GHz DC–2.0 GHz VSWR (I/O) Switching Characteristics4 Rise, Fall (10/90% or 90%/10% RF) On, Off (50% CTL to 90%/10% RF) Video Feedthru VHigh = -5 V For Two-tone Input Power +5 dBm VHigh = -5 V VLow = 0 to 0.2 V @ 20 µA Max.
