Description
Skyworks ceramic Chip on Board (COB) mixer quads are
designed for high-performance RF and microwave receiver
applications. These devices utilize Skyworks advanced silicon
beamless Schottky technology, combined with precision ceramic
COB assembly techniques, to achieve a high degree of device
reliability in commercial applications.
Characteristic Value
Maximum current (IMAX) 50 mA
Power dissipation (PD) CW 75 mW/junction
Storage temperature (TST) -65 °C to +175 °C
Operating temperature (TOP) -65 °C to +150 °C
Electrostatic Discharge (ESD) Class 0
Human Body Model (HBM)
Absolute Maximum Ratings
Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
Skyworks Green products are lead (Pb)-free, RoHS
(Restriction of Hazardous Substances)-compliant,
conform to the EIA/EICTA/JEITA Joint Industry Guide
(JIG) Level A guidelines, and are free from antimony
trioxide and brominated flame retardants.
