Combiner 1.65–2.45 GHz
DATA SHEET
Features
●Broadband: 1.65–2.45 GHz
●Low insertion loss
●Available in small SOIC-8 package or lead (Pb)-free,
RoHS-compliant package
Description
The PD4W18-12 is a monolithic four-way in-phase hybrid
junction optimized for the 1.71–1.99 GHz band that performs
very well from 1.65–2.45 GHz. It offers low loss, high isolation,
good input and output impedance matching and exceptional
phase and amplitude balance. It is available in the SOIC-8
package and a lead (Pb)-free SOIC-8 package.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

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.
