Description
M/A-COM’s DS52-0003 is an IC based monolithic power
splitter in a low cost SOIC-8 plastic package. This 2-way
device is ideally suited for applications where small size,
low profile and low cost, without sacrificing
performance, are required. Typical applications include
base station, portables and PCMCIA cards for wireless
data and spread spectrum applications. Available in tape
and reel.
The DS52-0003 is fabricated using a passive-integrated
circuit process. The process features full chip passivation
for increased performance and reliability.
