Description
M/A-COM's DS52-0008 is an IC-based monolithic power divider
using M/A-COM's GMIC technology in a low cost SOT-26
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 personal communications systems and other
communication applications where size and PCB real estate are at
a premium. Available in Tape and Reel.
The DS52-0008 is fabricated using a passive-integrated circuit
process. The process features full-chip passivation for increased
performance and reliability.
