Description
M/A-COM’s DS58-0002 is an IC-based monolithic power
divider in low cost SSOP-20 plastic packages. This 8-way
power divider is ideally suited for applications where
PCB real estate is at a premium and part count reduction
and cost are critical. Typical applications include base
station switching networks and other cellular equipment,
including subscriber units. Available in tape and reel.
The DS58-0002 is fabricated using a passive-integrated
circuit process. The process features full chip passivation
for increased performance and reliability.
