Description The AA264-87 is a 4 bit, single positive control GaAs IC FET digital attenuator in a low cost TSSOP-16 package. The attenuator requires external DC blocking capacitors, positive supply voltage (VS) and four individual positive control voltages (V1–V4). The AA264-87 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data and wireless local loop gain control circuits. 0.009 (0.22 mm) REF. 0.035 (0.90 mm) + 0.006 (0.15 mm) / -0.004 (-0.10 mm) 0.006 (0.15 mm) MAX. 0.002 (0.05 mm) MIN. 0.024 (0.60 mm) ± 0.006 (0.15 mm) Electrical Specifications at -40°C to +85°C (0, +5 V) Parameter1 Insertion Loss Attenuation Range Attenuation Accuracy2 0.5–1.0 GHz 0.5–2.0 GHz 0.5–2.0 GHz VSWR (I/O)3 Rise, Fall (10/90% or 90/10% RF) On, Off (50% CTL to 90/10% RF) Video Feedthru VS = +3 V VS = +5 V For Two-tone Input Power +5 dBm VS = +3 V VS = +5 V 0.5–2.0 GHz 0.5–2.0 GHz 0.5–2.0 GHz 0.5–2.0 GHz +15 +21 +36 +37 0.5–0.8 GHz 0.8–2.0...
