Description
M/A-COM's DS52-0004 is an IC-based monolithic power divider in
a low cost SOIC-8 plastic package. This 2-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 base station switching networks and
other communication applications where size and PCB real estate are
a premium. Available in tape and reel.
The DS52-0004 is fabricated using a passive-integrated circuit
process. The process features full-chip passivation for increased
performance and reliability.
