Description The AA226-87 is a 4 bit, single positive control GaAs IC FET digital attenuator. It requires DC blocking capacitors, positive supply voltage (VS) and four individual positive bit control voltages (V1–V4). The AA226-87 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 Condition Frequency 0.5–1.0 GHz 1.0–2.0 GHz 2.0–2.5 GHz 0.5–1.0 GHz 1.0–2.5 GHz VSWR (I/O)3 Switching Characteristics4 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 0.5–2.5 GHz 0.5–2.5 GHz 0.5–2.5 GHz 0.5–2.5 GHz +20 +24 +43 +44 0.5–2.5 GHz Min.
