Description
M/A-COM’s DS53-0005 is an IC-based monolithic power divider
using M/A-COM’s GMIC technology in a low cost SOIC-8 plastic
package. This 3-way power divider is ideally suited for
applications where small size, low insertion loss, superior phase/
amplitude tracking and low cost are required. Typical applications
include personal communication systems and other commun-
ication applications where size and PCB real estate are at a
premium. Available in tape and reel.
The DS53-0005 is fabricated using a passive-integrated circuit
process. The process features full-chip passivation for increased
performance and reliability.
