GaAs IC 3 Bit Digital Attenuator
4 dB LSB Positive Control 0.75–2 GHz
Preliminary
Features
s Attenuation in 4 dB Steps to 28 dB
with High Accuracy
s Single Positive Control Voltage
for Each Bit
s +3 V to +5 V Operation
s Small Low Cost MSOP-8 Plastic Package
Description
The AA100-59 is a 3 bit, single positive control, 4 dB step
GaAs IC FET digital attenuator in a low cost MSOP-8
plastic package. For positive operation external DC
blocking capacitors are required on all RF ports. The
AA100-59 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.
