Description
The SKY12324-73 is a 2-bit digital attenuator fabricated with
Skyworks GaAs PHEMT technology. The two attenuation bits, 4
and 8 dB, can be independently switched into or out of the signal
path according to the magnitudes of the control voltages applied
to the two high-impedance control voltage inputs. The RF ports
are internally matched to 50 Ω and are fully bilateral. The
SKY12324-73 is packaged in the SOT-6 package.
The SKY12324-73 is ideally suited for use in applications where
low insertion loss, excellent attenuation accuracy and excellent
intermodulation distortion performance are required. These appli-
cations include cellular telephone base stations, test instruments
and wireless data level control circuits.
A populated evaluation board is available.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
