Description
The AA102-80 is a 5-bit, single positive control GaAs IC FET dig-
ital attenuator in a low-cost SSOP-16 package. This attenuator
has an LSB of 0.5 dB and a total attenuation of 15.5 dB. The
attenuator requires external DC blocking capacitors, positive
supply voltage (V
S
) and five individual bit control voltages (V
1
–V
5
).
It is particularly suited where high attenuation accuracy, low
insertion loss and low intermodulation products are required.
Typical applications include base station, wireless data, and wire-
less local loop gain level control circuits.
DC blocking capacitors (C
BL
) and biasing resistor must be supplied externally for positive
voltage operation.
