Description
M/A-COM's DS52-0002 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 DS52-0002 is fabricated using a passive-integrated
circuit process. The process features full-chip passivation
for increased performance and reliability.
